This tutorial explains how to use MATCH function in Excel with formula examples. It also shows how to improve your lookup formulas by a making dynamic formula with VLOOKUP and MATCH.
In Microsoft Excel, there are many different lookup/reference functions that can help you find a certain value in a range of cells, and MATCH is one of them. Basically, it identifies a relative position of an item in a range of cells. However, the Excel MATCH function can do much more than its pure essence.
The MATCH function in Excel searches for a specified value in a range of cells, and returns the relative position of that value.
The syntax for the Excel MATCH function is as follows:
Lookup_value (required) - the value you want to find. It can be a numeric, text or logical value as well as a cell reference.
Lookup_array (required) - the range of cells to search in.
Match_type (optional) - defines the match type. It can be one of these values: 1, 0, -1. The match_type argument set to 0 returns only the exact match, while the other two types allow for approximate match.
- 1 or omitted (default) - find the largest value in the lookup array that is less than or equal to the lookup value. Requires sorting the lookup array in ascending order, from smallest to largest or from A to Z.
- 0 - find the first value in the array that is exactly equal to the lookup value. No sorting is required.
- -1 - find the smallest value in the array that is greater than or equal to the lookup value. The lookup array should be sorted in descending order, from largest to smallest or from Z to A.
To better understand the Excel MATCH function, let's make a simple formula based on this data: students names in column A and their exam scores in column B, sorted from largest to smallest. To find out where a specific student (say, Laura) stands among others, use this simple formula:
=MATCH("Laura", A2:A8, 0)
Optionally, you can put the lookup value in some cell (E1 in this example) and reference that cell in your Excel Match formula:
=MATCH(E1, A2:A8, 0)
As you see in the screenshot above, the student names are entered in an arbitrary order, and therefore we set the match_type argument to 0 (exact match), because only this match type does not require sorting values in the lookup array. And our Match formula tells us that Laura has the 4th best score among all students.
4 things you should know about Excel MATCH
As you have just seen, using MATCH in Excel is easy. However, as is the case with nearly any Excel function, there are a few specificities that you should be aware of:
- The MATCH function returns the relative position of the lookup value in the array, not the value itself.
- MATCH is case-insensitive, meaning it does not distinguish between lowercase and uppercase characters when dealing with text values.
- If the lookup array contains several occurrences of the lookup value, the position of the first value is returned.
- If the lookup value is not found in the lookup array, the #N/A error is returned.
Now that you know the basic uses of the Excel MATCH function, let's discuss a few more formula examples that go beyond the basics.
Like many other Excel functions, MATCH understands the following wildcard characters:
- Question mark (?) - replaces any single character
- Asterisk (*) - replaces any sequence of characters
A Match formula with wildcards comes useful in situations when you want to match not the entire text string, but only some characters or some part of the string. To illustrate the point, consider the following example.
Supposing you have a list of reginal resellers and their sales figures for the past month. You want to find a relative position of a certain reseller in the list but you cannot remember his name exactly, though you do remember a few first characters.
Assuming the reseller names are in the range A2:A11, and you are searching for the name that begins with "car", the formula goes as follows:
To make our Match formula more versatile, you can type the lookup value in some cell (E1 in this example), and concatenate that cell with the wildcard character, like this:
As shown in the screenshot below, the formula returns 2, which is the position of "Carter":
To replace just one character in the lookup value, use the "?" wildcard operator, like this:
The above formula will match the name "Baker" and rerun its relative position, which is 5.
As mentioned in the beginning of this tutorial, the Excel MATCH function doesn't distinguish uppercase and lowercase characters. To make a case-sensitive Match formula, use MATCH in combination with the EXACT function that compares cells exactly, including the character case.
The generic case-sensitive formula to match data in Excel is this:
The formula works with the following logic:
- The EXACT function compares the lookup value with each element of the lookup array. If the compared cells are exactly equal, the function returns TRUE, FALSE otherwise.
- And then, the MATCH function compares TRUE (which is its lookup_value ) with each value in the array returned by EXACT, and returns the position of the first match.
Please bear in mind that it's an array formula that requires pressing Ctrl + Shift + Enter to be completed correctly.
Assuming your lookup value is in cell E1 and the lookup array is A2:A9, the formula is as follows:
The following screenshot shows the case-sensitive Match formula in Excel:
Checking two lists for matches and differences is one of the most common tasks in Excel, and it can be done in a variety of ways. An ISNA/MATCH formula is one of them:
=IF(ISNA(MATCH(1st value in List1, List2, 0)), "Not in List 1", "")
For any value of List 2 that is not present in List 1, the formula returns "Not in List 1". And here's how:
- The MATCH function searches for a value from List 1 within List 2. If a value is found, it returns its relative position, #N/A error otherwise.
- The ISNA function in Excel does only one thing - checks for #N/A errors (meaning "not available"). If a given value is an #N/A error, the function returns TRUE, FALSE otherwise. In our case, TRUE means that a value from List 1 is not found within List 2 (i#N/A error is returned by MATCH).
- Because it may be very confusing for your users to see TRUE for values that do not appear in List 1, you utilize the IF function to display "Not in List 1" instead, or whatever text you want.
Supposing you are comparing values in column B with values in column A, the formula takes the following shape (where B2 is the topmost cell):
=IF(ISNA(MATCH(B2,A:A,0)), "Not in List 1", "")
As you remember, the MATCH function in Excel is case-insensitive by itself. To get it to distinguish the character case, embed the EXACT function in the lookup_array argument, and remember to press Ctrl + Shift + Enter to complete this array formula:
=IF(ISNA(MATCH(TRUE, EXACT(A:A, B2),0)), "Not in List 1", "")
The following screenshot shows both formulas in action:

This example assumes you already have some basic knowledge of Excel VLOOKUP function. And if you do, chances are that you've run into its numerous limitations (the detailed overview of which can be found in Why Excel VLOOKUP is not working) and are looking for a more robust alternative.
One of the most annoying drawbacks of Excel VLOOKUP is that it stops working after inserting or deleting a column within a lookup table. This happens because VLOOKUP pulls a matching value based on the number of the return column that you specify (index number). Because the index number is "hard-coded" in the formula, Excel is unable to adjust it when a new column(s) is added to or deleted from the table.
The Excel MATCH function deals with a relative position of a lookup value, which makes it a perfect fit for the col_index_num argument of VLOOKUP. In other words, instead of specifying the return column as a static number, you use MATCH to get the current position of that column.
To make things easier to understand, let's use the table with students' exam scores again (similar to the one we used at the beginning of this tutorial), but this time we will be retrieving the real score and not its relative position.
Assuming the lookup value is in cell F1, the table array is $A$1:$C$2 (it's a good practice to lock it using absolute cell references if you plan to copy the formula to other cells), the formula goes as follows:
=VLOOKUP(F1, $A$1:$C$8, 3, FALSE)
The 3rd argument (col_index_num) is set to 3 because the Math Score that we want to pull is the 3rd column in the table. As you can see in the screenshot below, this regular Vlookup formula works well:
But only until you insert or delete a column(s):
So, why the #REF! error? Because col_index_num set to 3 tells Excel to get a value from the third column, whereas now there are only 2 columns in the table array.
To prevent such things from happening, you can make your Vlookup formula more dynamic by including the following Match function:
- E2 is the lookup value, which is exactly equal to the name of the return column, i.e. the column from which you want to pull a value (Math Score in this example).
- A1:C1 is the lookup array containing the table headers.
And now, include this Match function in the col_index_num argument of your Vlookup formula, like this:
=VLOOKUP(F1,$A$1:$C$8, MATCH(E2,$A$1:$C$1, 0), FALSE)
And make sure it works impeccably no matter how many columns you add or delete:
In the screenshot above, I locked all cell references for the formula to work correctly even if my users move it to another place in the worksheet. A you can see in the screenshot below, the formula works just fine after deleting a column; furthermore Excel is smart enough to properly adjust absolute references in this case:
In a similar manner, you can use the Excel Match function to improve your HLOOKUP formulas. The general principle is essentially the same as in case of Vlookup: you use the Match function to get the relative position of the return column, and supply that number to the row_index_num argument of your Hlookup formula.
Supposing the lookup value is in cell B5, table array is B1:H3, the name of the return row (lookup value for MATCH) is in cell A6 and row headers are A1:A3, the complete formula is as follows:
=HLOOKUP(B5, B1:H3, MATCH(A6, A1:A3, 0), FALSE)
As you have just seen, the combination of Hlookup/Vlookup & Match is certainly an improvement over regular Hlookup and Vlookup formulas. However, the MATCH function doesn't eliminate all their limitations. In particular, a Vlookup Match formula still cannot look at its left, and Hlookup Match fails to search in any row other than the topmost one.
To overcome the above (and a few other) limitations, consider using a combination of INDEX MATCH, which provides a really powerful and versatile way to do lookup in Excel, superior to Vlookup and Hlookup in many respects. The detailed guidance and formula examples can be found in INDEX & MATCH in Excel - a better alternative to VLOOKUP.
