Excel array formula examples for beginners and advanced users

Array formulas are one of the most confusing features in Excel, and yet one of the most intriguing and exciting. Mastering Excel array formulas is a long road and last week we took the first steps by learning the basics of array functions and formulas in Excel.

However, like with any other skill, the road to mastery is paved with practice. So, today we will be focusing on advanced Excel array formula examples and try to make them both meaningful and fun.

Example 1. Count cells that meet certain condions

The introduction of SUMIF and COUNTIF functions as well as their plural counterparts in Excel 2007 made the use of array formulas superfluous in many scenarios. However, there are tasks where an array formula is the most effective, if not the only, solution.

Suppose you have 2 columns of numbers, column A (planned) and column B (actual). And you want to count how many times column B is greater than or equal to column A when a value in column B is greater than 0.

This task requires comparing two ranges and this is exactly what Excel array formulas are designed for.

So, you express the conditions as (B2:B10>=A2:A10) and (B2:B10>0), join them using the asterisk (*) that acts as the AND operator in array formulas, and include this expression in the SUM function's argument:

=SUM((B2:B10>=A2:A10) * (B2:B10>0))
An Excel array formula to count cells that meet two conditions

Remember to press Ctrl + Shift + Enter to enter the Excel array formula correctly.

The next couple of paragraphs are intended for those who like looking under the hood. If you are not interested in tech details, you can skip right to the next formula example.

For better understanding of this formula in particular and Excel array formulas in general, let's select the two expressions within the SUM function's parentheses in the formula bar, and press F9 to view the arrays behind the formula parts. If you want more information on how the F9 key works, please check out Evaluating portions of an array formula with F9.

So, what we have here is two arrays of Boolean values, where TRUE equates to 1 and FALSE equates to 0. Since we are using the AND array operator (*) in the formula, SUM will add up only those rows that have TRUE (1) in both arrays, as shown in the screenshot below:
Select portions of the formula and press F9 to view the arrays behind the formula parts.

Note. Not all Excel functions that support arrays can convert TRUE and FALSE into 1 and 0. In more complex array formulas, you might need to use a double dash (--), which is technically called the double unary operator, to convert non-numeric Boolean values to numbers.

Including a double dash in the above formula won't do any harm either, it will just keep you on the safe side: =SUM(--(B2:B10>=A2:A10) * (B2:B10>0))

And here is a more sophisticated Excel array formula example that absolutely requires the use of the double unary operator.

Example 2. Using several functions in Excel array formulas

Array formulas can work with several Excel functions at a time and perform multiple calculations within a single formula.

For example, if you have a table listing multiple product sales by several salesmen, and you want to know the maximum sale made by a given person for a given product, you can write an array formula based on the following pattern:

=MAX(IF((salesmen_range="name") * (products_range="name"), sales_range,""))

Assuming that the sales person names are in column A, product names are in column B and sales are in column C, the following formula returns the largest sale Mike has made for Apples:

=MAX(IF(($A$2:$A$9="mike") * ($B$2:$B$9="apples"), $C$2:$C$9,""))

Naturally, you can replace the names in the formula with cell references so that your users can simply type the names in certain cells without modifying your array formula:
Using several functions in Excel array formulas

In the screenshot above, the following Excel array formulas are used (don't forget to press Ctrl + Shift + Enter to enter them correctly):

Maximum: =MAX(IF(($A$2:$A$9=$F$1) * ($B$2:$B$9=$F$2), $C$2:$C$9,""))

Minimum: =MIN(IF(($A$2:$A$9=$F$1) * ($B$2:$B$9=$F$2), $C$2:$C$9,""))

Average: =AVERAGE(IF(($A$2:$A$9=$F$1) * ($B$2:$B$9=$F$2), $C$2:$C$9,""))

Total: =SUM(IF(($A$2:$A$9=$F$1) * ($B$2:$B$9=$F$2), $C$2:$C$9,""))

Example 3. Array formula to count all characters in a range

This array formula example shows how you can count the number of characters, including spaces, in a range of cells.

The formula is as simple as this:


You use the LEN function to return the length of the text string in each individual cell, and then you use the SUM function to add up those numbers.

For example, the array formula =SUM(LEN(A1:A10)) calculates the total number of all chars with spaces in range A1:A10.

Example 4. Array formula to count specific character(s) in a range

If you want to know how many times a given character or a group of characters appears in a specified range of cells, an array formula with the LEN function can help again. In this case, the formula is a bit more complex:

=SUM((LEN(range) - LEN(SUBSTITUTE(range, character, ""))) / LEN(character))

And here is a practical example. Suppose, you have a list of orders where one cell may contain several order numbers separated by commas or any other delimiter. There are several order types and each has its own unique identifier - the first character in an order number.

Assuming that orders are in cells B2:B5 and the unique identifier in E1, the formula is as follows:

=SUM((LEN(B2:B5) - LEN(SUBSTITUTE(B2:B5, E1, ""))) / LEN(E1))
Array formula to count any given character(s) in a ranges

At the heart of this formula, the SUBSTITUTE function replaces all occurrences of the specified character with an empty string ("").

The substituted string is fed to the LEN function to get the string length without the character of interest ("K" in this example). And then, you subtract the length of the substituted string from the original string's length. The result of this operation is an array of character counts, one per cell, which you divide by the substring length. The operation of division is not strictly necessary when you count a single character like in this example. But if you are counting the occurrences of a specific substring in a range (e.g. orders beginning with "KM"), you do need to divide by the substring length, otherwise each character in the substring will be counted individually.

Finally, you use SUM to add up the individual counts.

Example 5. Sum values in every other or Nth row

If you want to sum every other or every Nth row in a table, you will need the SUM and MOD functions combined in an array formula:

=SUM((--(MOD(ROW(range), n)=0)) * (range))

The MOD function returns the remainder rounded to the nearest integer after the number is divided by the divisor. We embed the ROW function into it to get the row's number, and then divide it by the Nth row (e.g. by 2 to sum every second cell) and check if the remainder is zero. If it is, then the cell is summed.

The double unary operator (--) is used to convert non-numeric Boolean values TRUE and FALSE returned by MOD into 1 and 0 for the SUM function to be able to add up the numbers.

For example, to count every other cell in range B2:B10, you use one of the following formulas:

Count even rows (2nd, 4th, etc.):
=SUM((--(MOD(ROW($B2:B10), 2)=0))*(B2:B10))

Count odd rows (1st, 3rd, etc.):
=SUM((--(MOD(ROW($B2:B10), 2)=1))*(B2:B10))

To get a universal formula that can sum values in any Nth rows that you specify and work correctly with any ranges regardless of their location in a worksheet, the formula has to be improved a little further:

=SUM((--(MOD((ROW($B$2:$B$7)-ROW($B$2)), E1)=E1-1))*($B$2:$B$7))

Where E1 is every N row you want to sum.
An array formula to sum values in every other or N<sup>th</sup> row

Example 6. Perform different calculations on numbers within different ranges

Here is a typical situation for many vendors - the unit price varies depending on the purchased quantity, and your goal is to write a formula that calculates the total price for any amount input in a specific cell.
Source data

This task can be easily accomplished by using the following nested IF formula:

=B8*IF(B8>=101,B6, IF(B8>=50, B5, IF(B8>=20, B4, IF( B8>=11, B3, IF(B8>=1, B2, "")))))

However, this approach has a significant limitation. Because the formula references each price in cells B2 to B6 individually, you will have to update the formula as soon as your users change any of the existing ranges or add a new quantity range.

To make the formula more flexible, operate on arrays rather than individual cells. In this case, no matter how many values are changed, added or deleted, you will only have to update a single range reference in the formula.

=SUM(B8*(B2:B6) * (--(B8>=VALUE(LEFT(A2:A6,FIND(" ",A2:A6))))) * (--(B8<=VALUE(RIGHT(A2:A6,LEN(A2:A6) - FIND(" to ",A2:A6)-LEN(" to" ))))))
Array formula to perform different calculations on numbers within different ranges

The detailed break down of this formula will probably require a separate article, so I will make just a quick overview of the logic. If you select individual parts of the formula in the formula bar and press F9, you will see that it boils down to evaluating the following 3 arrays (provided the quantity in B8 is 100 like in the screenshot above):


The first 5-element array is nothing else than the price numbers in cells B2:B6. And the last 2 arrays of 0's and 1's determine which price will be used in calculation. So, the main question is - where do these two arrays come from and what do they mean?

The formula includes 2 VALUE functions: (B8>=VALUE())*(B8<=VALUE())

The 1st function checks if the value in B8 is greater than or equal to the lower bound of each "unit quantity" range, and the 2nd one checks if B8 is less than or equal to the upper bound of each range (the combinations of LEFT, RIGHT, FIND and LEN functions are used to extract the upper and lower bound values). As a result, you get 0 if the condition is not met, and 1 if the condition is met.

Finally, the SUM function multiplies the quantity in B8 by each element of the price array (B2:B6) and by each elements of the 0's and 1's arrays. Since multiplying by 0 always gives 0, only one price is used in the final calculation - the element that has 1's in the last two arrays.

In this example, the quantity is multiplied by $13 that corresponds to "50 to 100" amount range. It is the 4th item of the price array (cell B5 in range B2:B6), and it is the only element that has 1's in the last two arrays.

For the formula to work correctly, be sure to check these two things:

  • The quantities in A2:A6 should constitute a contiguous range such that no value is left out.
  • All quantities in A2:A6 have to be entered in this specific pattern "X to Y" because it is hard-coded in the formula. If your quantities are entered in a different way, say "1 - 10", then replace " to" with " -" in the formula.

If you want to display an "Out of range" message when the quantity input in B8 is outside the amount range, include the following IF statement:

=IF(AND(B8>=VALUE(LEFT(A2,FIND(" ",A2))), B8<=VALUE(RIGHT(A6,LEN(A6) - FIND(" to ",A6)-LEN(" to" )))), SUM(…))

This complex If function does a very simple thing - checks if the value in B8 is greater than or equal to the lower bound in A2 and less than or equal to the upper bound in A6. In other words, it tests this condition: AND(B8>=1, B8<=200).

The complete formula goes as follows:

=IF(AND(B8>=VALUE(LEFT(A2,FIND(" ",A2))), B8<=VALUE(RIGHT(A6,LEN(A6)-FIND(" to ",A6)-LEN(" to" )))), SUM(B8*(B2:B6)*(--(B8>=VALUE(LEFT(A2:A6,FIND(" ",A2:A6)))))*(--(B8<=VALUE(RIGHT(A2:A6,LEN(A2:A6)-FIND(" to ",A2:A6)-LEN(" to" )))))), "Out of range")
Array formula to perform different calculations on numbers within limited ranges

Example 7. User-defined functions in Excel array formulas

This example is purposed for power users that have some knowledge of Excel VBA macros and user-defined functions.

You can utilize your own user-defined function in Excel array formulas, provided that a given function supports calculations in arrays.

For example, one of our Excel gurus wrote a function called GetCellColor that can get a color of all cells in a range, exactly as its name suggests. You can grab the function's code from this article - Sum and count colored cells in Excel.

And now, let's see how you can use the GetCellColor function in an array formula. Suppose you have a table with a color coded column and you want to sum the values that meet several conditions, including a cell's color. As an example, let's find the total of "green" and "yellow" sales made by Neal:
Using user-defined functions in Excel array formulas

As demonstrated in the image above, we use the following Excel array formula:

=SUM(--($A$2:$A$10=$F$1) * ($C$2:$C$10) * (--(GetCellColor($C$2:$C$10)=GetCellColor($E$2))))

Where cell F1 is the sales person name and E2 is the color pattern.

The formula sums cells in the range C2:C10 if the following 2 conditions are met:

  • $A$2:$A$10=$F$1 - checks if a cell in column A matches the seller name in F1, which is Neal in this example.
  • GetCellColor($C$2:$C$10)=GetCellColor($E$2) - we use the custom user-defined function to get the color of cells C2 through C10, and check if it matches the color pattern in E2, green in this case.

Please pay attention that we use the double unary operator with both of the above expressions in order to convert the Boolean values TRUE and FALSE they return into 1's and 0's the SUM function can operate on. If both conditions are met, i.e. two 1's are returned, SUM adds up the sales amount from a corresponding cell in column C.

More Excel array formula examples

And here are a few more examples of Excel array formulas that might be helpful.

Excel array formulas - limitations and alternatives

Array formulas are by far one of the most powerful features in Excel, but not all-powerful. Here are the most critical limitations of arrays in Excel.

1. Large arrays may slow down Excel

Though Microsoft Excel does not impose any limit on the size of arrays you use in your worksheets, you are limited by memory available on your computer because recalculating formulas with large arrays is time consuming. So, in theory, you can create huge arrays consisting of hundreds or thousands of elements, in practice this is not recommended because they can drastically slow your workbooks.

2. Entire column arrays are not allowed

You are not allowed to create an array that includes a whole column or several columns for an obvious reason explained above. Array formulas in Excel are very resource-hungry and Microsoft is taking preventive measures against Excel's freezing.

3. Limit to array formulas referring to another sheet

In Excel 2003 and earlier versions, a given worksheet could contain a maximum of 65,472 array formulas referring to another sheet. In modern versions of Excel 2013, 2010 and 2007, cross-worksheet array formulas are limited by available memory only.

4. Debugging array formulas

If your array formula returns an incorrect result, make sure you pressed Ctrl + Shift + Enter when entering it. If you did, select parts of the formula and press the F9 key to evaluate and debug them.

5. Alternatives to array formulas.

If you find Excel array formulas too complex and confusing, you can use one of Excel functions that can naturally process arrays of data (without pressing Ctrl + Shift + Enter). A good example is the SUMPRODUCT function that multiplies values in the specified arrays and returns the sum of those products. Another example is Excel INDEX function with an empty value or 0 in the row_num or col_num argument to return an array of values from the entire column or row, respectively.

  1. Hi,

    Very good perspective on Array Formulas ...

    Can an Array Formula replicate the "Step" feature offered by the very recent Sequence function ?

    The objective for the Array Formula is to generate {1,4,7,10,13} (working with Excel 2016)

    Thanks for your insight

  3. Hi,
    I'm trying to make a list where the value increases based on some other results or not. It references the cell above each value, and the array spill in 365 mistakenly claims that there is a circular reference. How to fix?
    C5 =0
    C6 =if(C5:C100>5,0,C5:c100+1)

    The actual boolean is a bit more complicated, and many thousands of rows, but it shows the problem.
    This really seems to limit the usability of autospill if it cannot be fixed somehow.

    Thanks, looking forward to any insights

  6. My task is to search a range of cells for any that contain a text string ("contain", hence Match will not work) and return the value in a different column (not necessarily adjacent); but return the values are not to be in one column down several rows, but in one row across several columns. I know how can generate the list using Match in a column. I have two problems.

    Problem 1 is that I cannot generate the list searching, not for a Match, but for cells containing a specified text string.

    Problem 2 is that I cannot generate the return values in a single row

  7. Hi Svetlana,

    I think I may have a complicated question. Simply put, I would like to compare an array with another array. I've solved the issue with comparing uneven arrays such as if one contains 100 and another 103, but I realized that when I compare one array to another, it compares the element in each array at the same position. In other words, array1={1,2,3} and array2={1,2,3,4,5}. =SUM(array1*array2) will equal an "#N/A" error. After I programmed a way to remove all "#N/A" errors, the =SUM(array1*array2) formula results in ={(1*1)+(2*2)+(3*3)}=14. However, I'm looking for something more like ={(1*1)+(1*2)+(1*3)+(2*1)+(2*2)+(2*3)+(3*1)+(3*2)+(3*3)}=90 (you can ignore the truncated numbers from array2). Is that possible?

    The parameters:
    1) I have element variable changing arrays (the array sizes are always increasing at a different rate) so you can't hard code, assume a fixed array size, or any rate change correlation between the two arrays.
    2) The code has to be programmed into a single cell without any "helper rows/columns."
    3) No outside programs can be used such as VBA, C==, Java, etc.
    4) The functions won't always be an excel "SUM" function. This array comparison code should work with all excel functions that allow arrays such as: =SUM(IF(array1....., =COUNT(IF(array1..., etc.
    5) At least 2 uneven array sizes are required to be directly compared to one another.

  8. In the above tutorial you use a User-Defined function called "GetCellColor". I assume that since it is Alexander Frolov design we can NOT utilize it within the tutorial review. It's a non-function on my laptop, Correct? If so, why not advise within the tutorial? In an attempt to understand your tutorial I recreate each and very Example to ensure I understand the section. I can NOT get Example 7 to work. It comes back with an error message "NAME".

    • Hello Gregg,

      Thank you for your comment.

      To be able to use this function, you need to add its VBA code to your Excel. The code and the detailed instructions are provided in a separate article: How to count and sum cells by color in Excel.

      Because the focus of this tutorial is on array formulas, we did not replicate the code here. Instead, I included the above link in the corresponding example.

  9. I would like to use these dynamic array functions. What should I do to have a version of excel available that can run these functions? I have an office 365 Business subscription

  10. What do the 3 #'s at the end of this array mean....I forgot!
    =SUM(IF('4th QTR'!$B$2:$B$511="EJP",IF('4th QTR'!$E$2:$E$511=2,1,0)))

    I think the 0 means there is no number in the cells and I think the 1 means there is a # in the cells and all 1's in response to this array will be added together, but I forgot what the 2 means?

    I've stumbled on your site by searching, and I would really like to more about the excel program. It appears I found the right place, I do have a question? Is it possible to create an excel sheet that would filter, highlight or whatever the term is that would allow groups of numbers to show up? I know this vague but I will try to explain. Ex: 1_2_3_4_5_ 1 being a mirror to 6,2
    6 7 8 9 0
    to 7,3 to 8 and so on, so if I had 1,3,4 in one group is it possible to show
    6,8,9 if it were together in another group?

    I have problem related, I think, to using IF function or IFS.
    I have a Pivot filter including 3 options, means I can select 1 or All or Multiple product categories. I am using SUMIFS to extract the data from Excel table, and filter using Pivot filter. all working fine until I select 2 product categories, I eliminate the problem when selecting (ALL), but could not do that when I select 2 product categories, the result was all zero values. here is my function:


    my attempt was nested IF:

    but it dose not work, any help...

  25. I don't know if arrays can help me in this instance or what solution would in Excel, but here is the situation.

    I work at a dental office. Dental offices get paid only 1 of 2 ways, from a patient's insurance claims checks, or the patient pays out of pocket.

    So a patient's total account balance = the insurance balance + the patient balance.

    I am looking at the aging of accounts receivable, and there are 7 buckets in terms of time, 0 to 30 days old, 31 to 60, 61 to 90, 91 to 120, 121 to 150, 151 to 180 and 181+ days old or more as a catch all.

    I want to build a report that shows all 3 pieces for each patient:
    1. the total account balance by each of the 7 aging buckets
    2. the insurance balance portion only by each of the 7 aging buckets
    3. the patient balance portion only by each of the 7 aging buckets

    The dental software the office uses only gives perspective #1, so I have resorted to creating the other two perspectives in Excel.

    The part where I am stuck is when a patient has both types of balances, insurance and patient portion, but its a one to many relationship. For example, patient

    John Smith, could have an insurance portion balance in only 1 bucket, say 31 to 60 days old (for $128 as an example), but they have a patient portion balance (say $310) that is dispersed among 2 or more buckets, say the 121 to 150 day old bucket ($185) and the 181+ day old bucket ($125).

    What I want to do, what I am trying to do is have the insurance balance aging report read

    31 to 60, $128
    all other aging buckets on the insurance side for John Smith should show $0 or blank.

    The patient portion should read

    121 to 150, $185
    181+, $125
    all other aging buckets on the patient side for John Smith should show $0 or blank

    Two snags to this, the original output to the reporting software does something wonky when I dump it into Excel,

    1. it give the patient portion and insurance portion balances OUTSIDE the aging buckets, and disperses only the total account balances for each patient INSIDE or WITHIN the aging buckets.

    2. While an insurance balance portion can only be a positive number, a patient balance portion can either be positive or negative (negative meaning they have a credit on their account for future dental work, or we owe them money).


  26. Hello,
    Can you please tell me how to write this below formula in excel $E$5-SUM($C$5:C6) how we create this in excel function?
    Either manualy or by hitting somewhere in table.

  27. as I enter values in three rows a1,a2,a3 those values should befollowed to next sheetand as I press enter a1,a2,a3 should become 0 .as I reenter the values in a1,a2,a3 those values should get copied to next column b1,b2,b3
    like this it should continue everytime

  28. I'm trying to use the =SUMPRODUCT(--ISNUMBER(SEARCH(LOWER(town),LOWER(T2))))>0 formula, that looks at an array of say 100 items. Is there a way rather than coming back true or false, that the formula can tell me the cell content it matched to. e.g. "Sydney" Thanks!



    • Suppose cell address of A is A1 & last B has address A5. Then the formula will be-

      I think this will serve the purpose.

  30. Hi there!!!

    Something, that I think is curious, is why, in your fourth example, you put "/ LEN(E1)" in your formula. According to me, you didn't need it: You can obtain the same result without it. But, any way, if you have time and you like, would you like to explain me? To me it would be something very illustrative.

    Take care, and thanks for your knowledge.

    • Hi Sergio,

      Dividing by LEN(E1) is not needed when you count a single character like in the example you referred to. In situations when you want to count the occurrences of a specific substring in a range (i.e. a sequence of 2 or more characters), you need to divide by the substring length, otherwise each character in the substring will be counted individually (for example if you have entries like "cat-1", "cat-2", "dog-1, "dog-2", etc. and you want to get the total number of "cat" entries).

  31. Hi Team,
    i am a big fan of the nuggets on the website. i am trying to work on a problem which comprises of three parameters(columns) Date, Value,Outlier(0-outlier /1-safe value).I have to create a new column (say Output) which will have all normal value (Outlier = 1, in case there is a 0 it should have value corresponding to previous 1). I am not able to handle case when there are 3 or more sequential Outlier.
    Date Value Outlier Output
    1-Jan 355306 1 355306
    2-Jan 1283040 0 355306
    3-Jan 303244 1 303244
    4-Jan 668608 1 668608
    5-Jan 1249288 0 668608
    6-Jan 133452 0 668608
    7-Jan 1005512 1 1005512
    8-Jan 81904 0 1005512
    9-Jan 112200 0 1005512
    10-Jan 81780 0 1005512
    4-Jan 668608 1 668608

    Would appreciate your assistance with the above.

  33. hi there,

    I am trying to make a barcode scanner excel sheet. suppose in one coloum A, i have barcode numbers like 123456789, 987654321 etc and in colum B i have their names like product X, product Y etc. i want if i scan a barcode in column C and if it is present in the list A, it must be display its product name name from column B and if not present it must display any other message. can anyone help me out with a formula ?


    • If you want just to verify if Cx=Ax, then is really simple.


      Copy formula in all column C cells (your range, not full column C).

  34. Hello,

    My formula is "locked" in somewhere, result is as expected, but when i tried to copy paste and a little tweak to adjusted between rows, result get empty. And then i realized my formula is "locked" and depend on the C5 input instead of criteria as intended to get the result.

    Below is my array formula, please review it.

    To get a better view, here i attach the image https://i.stack.imgur.com/5ptWT.png

    Hope someone can make a review or direct me to somewhere, because i seems can't get the google keyword to my problem.
    Initially i'm trying to make a ledger from daily journal, so u must be alert what im attempting to achieve.
    Would u review it.

  35. I am trying to integrate the every "N" example to sum a quarterly recurring revenue stream.
    Sales occur every month, we just need to sum the months that correspond to the current cells cohorts. Making it even more challenging, the sum range needs to be variable based upon an intro month and lifespan in months.
    Formula currently:

    (make sure we have an item to sum)
    (this id's the item as quarterly)IF(IFERROR(INDEX(Setup!$B$63:$L$77,SMALL(IF(Setup!$B$63:$B$77=$B102,ROW(Setup!$L$63:$L$77)-62),ROW($A$1)),11),"")="Quarterly",
    (this gets the quarterly and returns the life span of the stream in years and * by 12)
    (adding the launch month)+IFERROR(INDEX(Setup!$B$63:$M$77,SMALL(IF(Setup!$B$63:$B$77=$B102,ROW(Setup!$M$63:$M$77)-62),ROW($A$1)),12),""))
    (Now we if current month < need to offset and have number of columns for offset)
    (True <= offset needed so sum from current column to every third cell to column C.),E102+IFERROR(INDEX($B$68:D$82,SMALL(IF($B$68:$B$82=$B102,ROW(D$68:D$82)-67),ROW($A$1)),E$66),""),0),0),

    (Current month is greater than life span + intro month so sum from current column, every third cell back life (span + intro month) columns)

    Yes, this is an array formula.

  36. Hi,

    I really need help! What does: =SUM(''!$B$9) means? From where does it pic up the figures?

    Thanks you in advance,


  37. Very clear and informative! Thank You!

I am trying to get a result that students have got above 60 among all the students where in the same column, there will be 40and50 and 60, absentees and fail student are there among these i trying to fetch a result that student like First class, Second class, and third class. pl. send answer as soon as possible.

  40. hello,

    your site is great and i found it very useful.

    would you have an examples of calculations such as this: =SUMIF([Timeline],"<="&[@Timeline],[Weighted Forecast]).

    Thanks a lot,


    • Hello, Ziv,

      For us to be able to assist you better, please describe your task in more detail and give more examples.

  41. Dear, I have amount in cell A Rs:642. I need formula that show in next cell (B) only that amount multiply by 25.

    For example: A B C A B C
    642 625 17 366 350 16

    • =sum(A1*25) this will do it for you.

  42. Never mind, I figured it out.

  43. I have a sheet with game scores on them. One column is the name of the visiting team, another is the visting teams score, and another is the home teams score. I haven't been able to figure out how to get the number of times the visiting team's score is greater than the home team's score when the visiting team is a certain team. For example, when the visiting team (col A) is Team A, how many times is col B (visiting team score) greater than col C (home team score).

    This seems simple to do, but I've yet to hit upon the right syntax.

  44. Beautiful article. Describes the issue very clearly. Thanks.

  45. Is there a way to combine an array's contents into one cell?
    Ex. {"One","Two","Three"} in one cell as OneTwoThree.
    If so, can this be done: One, Two, Three
    in a single cell from that array?

    If not, I'll write a UDF for what I'm looking to do.

  46. Hi Svetlana,
    Your article, methinks, is the best to start learning Array Formulas.
    Great job!
    Shall I expect an article that describes
    *Simplifying big formulas into small etc.?

    • Hi Prasad,

      Thank you so much for your kind feedback and the idea. I will give it a thought :)

  47. I like your site very much useful i found it very useful

      • this formula worked for me =SUM((LEN(C5:AF5)-LEN(SUBSTITUTE(C5:AF5, AH3,"")))/LEN(AH3))

        but when I Drag this formula for the below column.... this formula doesn't apply..... why is that..... this is exactly what I was looking for but at dragging the formula from top to bottom the formula changes and from C the formula goes to D and from AF5 it goes to AF6

        Example :

        Top Column = =SUM((LEN(C4:AF4)-LEN(SUBSTITUTE(C4:AF4, AH3,"")))/LEN(AH3))

        when I drag formula from top to bottom of the spreadsheet

        the formula changes to

        =SUM((LEN(C5:AF5)-LEN(SUBSTITUTE(C5:AF5, AH4,"")))/LEN(AH4))
