*In this tutorial, you will learn how to count unique values in Excel with formulas, and how to get an automatic count of distinct values in a pivot table. We will also discuss a number of formula examples for counting unique names, texts, numbers, cased-sensitive unique values, and more.*

When working with a large dataset in Excel, you may often need to know how many **duplicate** and **unique** values are there. And sometimes, you may want to count only the **distinct** (different) values.

If you have been visiting this blog on a regular basic, you already know the Excel formula to count duplicates. And today, we are going to explore different ways to count unique values in Excel. But for the sake of clarity, let's define the terms first.

**Unique**values - these are the values that appear in the list only once.**Distinct**values - these are all different values in the list, i.e. unique values plus 1^{st}occurrences of duplicate values.

The following screenshot demonstrates the difference:

And now, let's see how you can count unique and distinct values in Excel using formulas and PivotTable features.

## How to count unique values in Excel

Here's a common task that all Excel users have to perform once in a while. You have a list of data and you need to find out the number of unique values in that list. How do you do that? Easier than you may think :) Below you will find a few formulas to count unique values of different types.

### Count unique values in a column

Supposing you have a column of names in your Excel worksheet, and you need to count unique names in that column. The solution is to use the SUM function in combination with IF and COUNTIF:

*range*,

*range*)=1,1,0))

**Note**. This is an array formula, so be sure to press Ctrl + Shift + Enter to complete it. Once you do it, Excel will automatically enclose the formula in {curly braces} like in the screenshot below.

In this example, we are counting unique names in range A2:A10, so our formula takes the following shape:

`=SUM(IF(COUNTIF(A2:A10,A2:A10)=1,1,0))`

Further on in this tutorial, we are going to discuss a handful of other formulas to count unique values of different types. And because all those formulas are variations of the basic Excel unique values formula, it makes sense to break down the above formula, so you can fully understand how it works and tweak it for your data. If someone is not interested in technicalities, you can skip right to the next formula example.

#### How the Excel count unique values formula works

As you see, 3 different functions are used in our unique values formula - SUM, IF and COUNTIF. Looking from the inside out, here's what each function does:

- The COUNTIF function counts how many times each individual value appears in the specified range.
In this example,

`COUNTIF(A2:A10,A2:A10)`

returns the array`{1;2;2;1;2;2;2;1;2}`

. - The IF function evaluates each value in the array returned by COUNTIF, keeps all 1's (unique values), and replaces all other values with zeros.
So, the function

`IF(COUNTIF(A2:A10,A2:A10)=1,1,0)`

becomes`IF(1;2;2;1;2;2;2;1;2) = 1,1,0,`

which turns into the array`{1;0;0;1;0;0;0;1;0}`

where 1 is a unique value and 0 is a duplicate value. - Finally, the SUM function adds up the values in the array returned by IF and outputs the total number of unique values, which is exactly what we wanted.

**Tip.**To see what a specific part of your Excel unique values formula evaluates to, select that part in the formula bar and press the F9 key.

### Count unique text values in Excel

If your Excel list contains both numerical and text values, and you want to count only unique text values, add the ISTEXT function to the array formula discussed above:

`=SUM(IF(ISTEXT(A2:A10)*COUNTIF(A2:A10,A2:A10)=1,1,0))`

As you know, the Excel ISTEXT function returns TRUE if an evaluated value is text, FALSE otherwise. Since the asterisk (*) works as the AND operator in array formulas, the IF function returns 1 only if a value is both text and unique, 0 otherwise. And after the SUM function adds up all 1's, you will get a count of unique text values in the specified range.

Don't forget to press Ctrl + Shift + Enter to correctly enter the array formula, and you will get a result similar to this:

As you can see in the screenshot above, the formula returns the total number of unique text values, excluding blank cells, numbers, logical values of TRUE and FALSE, and errors.

### Count unique numeric values in Excel

To count unique numbers in a list of data, utilize an array formula like we've just used for counting unique text values, with the only difference that you embed ISNUMBER instead of ISTEXT in your unique values formula:

`=SUM(IF(ISNUMBER(A2:A10)*COUNTIF(A2:A10,A2:A10)=1,1,0))`

**Note.**Since Microsoft Excel stores dates and times as serial numbers, they are also counted.

### Count case-sensitive unique values in Excel

If your table contains case-sensitive data, the easiest way to count unique values would be creating a helper column with the following array formula to identify duplicate and unique items:

`=IF(SUM((--EXACT($A$2:$A$10,A2)))=1,"Unique","Dupe")`

And then, use a simple COUNTIF function to count unique values:

`=COUNTIF(B2:B10, "unique")`

## Count distinct values in Excel (unique and 1^{st} duplicate occurrences)

To get a count of distinct values in a list, use the following formula:

*range*,

*range*))

Remember, it's an array formula, and therefore you should press the Ctrl + Shift + Enter shortcut instead of the usual Enter keystroke.

Alternatively, you can use the SUMPRODUCT function and complete the formula in the usual way by pressing the Enter key:

*range*,

*range*))

For example, to count the distinct values in range A2:A10, you can go with either:

`=SUM(1/COUNTIF(A2:A10,A2:A10))`

Or

`=SUMPRODUCT(1/COUNTIF(A2:A10,A2:A10))`

#### How the Excel distinct formula works

As you already know, we use the COUNTIF function to find out how many times each individual value appears in the specified range. In the above example, the result of the COUNTIF function is the following array: `{2;2;3;1;2;2;3;1;3}`

.

After that, a number of division operations are performed, where each value of the array is used as a divisor with 1 as the dividend. This turns all duplicates values into fractional numbers corresponding to the number of duplicate occurrences. For example, if a value appears 2 times in the list, it generates 2 items in the array with a value of 0.5 (1/2=0.5). And if a value appears 3 times, it produces 3 items in the array with a value of 0.3(3). In our example, the result of `1/COUNTIF(A2:A10,A2:A10))`

is the array `{0.5;0.5;0.3(3);1;0.5;0.5;0.3(3);1;0.3(3)}`

.

Doesn't make much sense so far? That's because we haven't applied the SUM / SUMPRODUCT function yet. When one of these functions adds up the values in the array, the sum of all fractional numbers for each individual item always yields 1, no matter how many occurrences of that item exist in the list. And because all unique values appear in the array as 1's (1/1=1), the final result returned by the formula is the total number of all different values in the list.

### Formulas to count distinct values of different types

As is the case with counting unique values in Excel, you can use variations of the basic Excel count distinct formula to handle specific value types such as numbers, text, and case-sensitive values.

Please remember that all of the below formulas are array formulas and require pressing Ctrl + Shift + Enter.

#### Count distinct values ignoring empty cells

If a column where you want to count distinct values might contain blank cells, you should add an IF function that will check the specified range for blanks (the basic Excel distinct formula discussed above would return the #DIV/0 error in this case):

*range*<>"",1/COUNTIF(

*range*,

*range*), 0))

For example, to count distinct values in range A2:A10, use the following array formula:

`=SUM(IF(A2:A10<>"",1/COUNTIF(A2:A10, A2:A10), 0))`

#### Formula to count distinct text values

To count distinct text values in a column, we'll be using the same approach that we've just used to exclude empty cells.

As you can easily guess, we will simply embed the ISTEXT function into our Excel count distinct formula:

*range*),1/COUNTIF(

*range*,

*range*),""))

And here's a real-life formula example:

`=SUM(IF(ISTEXT(A2:A10),1/COUNTIF(A2:A10, A2:A10),""))`

#### Formula to count distinct numbers

To count distinct numeric values (numbers, dates and times), use the ISNUMBER function:

*range*),1/COUNTIF(

*range*,

*range*),""))

For example, to count all different numbers in range A2:A10, use the following formula:

`=SUM(IF(ISNUMBER(A2:A10),1/COUNTIF(A2:A10, A2:A10),""))`

#### Count case-sensitive distinct values in Excel

Similarly to counting case-sensitive unique values, the easiest way to count case-sensitive distinct values is to add a helper column with the array formula that identifies unique values including first duplicate occurrences. The formula is basically the same as the one we used to count case-sensitive unique values, with one small change in a cell reference that makes a great difference:

`=IF(SUM((--EXACT($A$2:$A2,$A2)))=1,"Distinct","")`

As you remember, all array formulas in Excel require pressing Ctrl + Shift + Enter.

After the above formula is finished, write a usual COUNTIF formula like `=COUNTIF(B2:B10, "distinct")`

to count distinct values:

If there is no way you can add a helper column to your worksheet, you can use the following complex array formula to count case-sensitive distinct values without creating an additional column:

`=SUM(IFERROR(1/IF($A$2:$A$10<>"", FREQUENCY(IF(EXACT($A$2:$A$10, TRANSPOSE($A$2:$A$10)), MATCH(ROW($A$2:$A$10), ROW($A$2:$A$10)), ""), MATCH(ROW($A$2:$A$10), ROW($A$2:$A$10))), 0), 0))`

## Count unique and distinct rows in Excel

Counting unique / distinct rows in Excel is akin to counting unique and distinct values, with the only difference that you use the COUNTIFS function instead of COUNTIF, which lets you specify several columns to check for unique values.

For example, to count unique or distinct names based on the values in columns A (First Name) and B (Last Name), use one of the following formulas:

**Formula to count unique rows:**

`=SUM(IF(COUNTIFS(A2:A10,A2:A10, B2:B10,B2:B10)=1,1,0))`

**Formula to count distinct rows:**

`=SUM(1/COUNTIFS(A2:A10,A2:A10,B2:B10,B2:B10))`

Naturally, you are not limited to counting unique rows based only on two columns, the Excel COUNTIFS function can process up to 127 range/criteria pairs.

## Count distinct values in Excel using a PivotTable

The latest versions of **Excel 2013** and **Excel 2016** have a special feature that allows counting distinct values automatically in a pivot table. The following screenshot gives an idea of how the Excel **Distinct Count** looks like:

To create a pivot table with the distinct count for a certain column, perform the following steps.

- Select the data to be included in a pivot table, switch to the
*Insert*tab,*Tables*group, and click the**PivotTable**button. - In the
*Create PivotTable*dialog, choose whether to place your pivot table in a new or existing worksheet, and be sure to select the**Add this data to the Data Model**checkbox.

- When your pivot table opens, arrange the Rows, Columns and Values areas the way you want. If you don't have much experience with Excel pivot tables, the following detailed guidelines may prove helpful: Creating a PivotTable in Excel.
- Move the field whose distinct count you want to calculate (
*Item*field in this example) to the*Values*area, click on it, and select**Field Value Settings…**from the drop-down menu:

- The
*Value Field Settings*dialog window will open, you scroll down to**Distinct Count**, which is the very last option in the list, select it and click*OK*.

You can also give a custom name to your Distinct Count if you want to.

Done! The newly created pivot table will display the distinct count like shown in the very first screenshot in this section.

**Tip.**After updating your source data, remember to update the PivotTable to bring the distinct count up to date. To refresh a pivot table, just click the

**Refresh**button on the

*Analyze*tab, in the

*Data*group.

I thank you for reading and hope to see you again next week. In the next article, we are going to discuss various ways to find, filter, extract and highlights unique values in Excel. Please stay tuned!

Hi,

Would you please help me on this scenario. I have a spreadsheet where column a shows patient name. Column b shows type of service. Column a have duplicate patient names since some patient gets more than one services. Now I need to identify( count) how many patients were receiving more than one services. Would you help me with the fomular? Or a way to do that. Thank you very much.

Hello Fiona,

You can do it in the following way:

1. Add the following formula, say in column C, to identify duplicate names:

=IF(COUNTIF($A$2:$A2, $A2)>1, "Duplicate", "")

Where A2 is the first cell in the Patient Names column.

2. Apply Excel's filter, filter out the unique name so that only duplicate names are visible, and copy those duplicate names to another sheet.

3. In that other sheet, use the following array formula to count distinct names (unique +1st duplicate occurrences). Remember to press Ctrl+Shift+Enter to complete the formula:

=SUM(1/COUNTIF(A2:A8,A2:A8))

Where A2 is the first and A8 is the last cell.

I've create a quick example for you, and you can download it here.

After filtering out duplicates, what you have are unique names. So, applying CountA(A2:A8) would give the count of those names. Why do we need to apply the array formula as mentioned by you? Any specific reason?

Hi John,

Fiona's task was to count how many patients were receiving more than one services. For this, we needed to get a list of duplicates names, not unique names, and then count how many different (distinct) names appear in that list. I've re-worded point 2 in my previous comment, and hope now it makes more sense.

For example, after filtering out the unique names, we get the following list of duplicate names: Peter, Maria, Peter, Rob, Maria. And now, we need an array formula mentioned above to count how many different names appear in this list (3 names). You can find the detailed explanation of the formula in How the distinct formula works.

hi,

How to count the number of distinct values. If the values are neither numbers nor text but the mix of both like 12000078fg?

Hello,

We download a report from Just Giving each time we have a donation and the format is not very easy to follow so we would just like to extract the information we need (eventually in a macro).

I would like to lookup all the distinct values in the user ID column, then calculate the total number of donations for each of the distinct ID values. I can then apply this formula to the other fee columns.

Any help would be much appreciated!

Many thanks,

Dani

Hi,

I don't see the item "Add this data to the data model" in the Create Pivot Table window. How come? I am using Excel 2010.

Hi Fab,

Regrettably, this option is not available in Excel 2010. It was introduced in Excel 2013, and also exists in Excel 2016. In earlier Excel versions, you can count unique values using formulas as demonstrated in the first parts of this tutorial.

I have Excel 2013, but the checkbox for "add this data to data model" is grayed-out and unchecked. Is there an Excel Add-in required to get this area functional?

Thanks,

Derek

Hi,

In Excel 2013 I have a table with more fields. The table is sorted on first field. In a new generated field of my table I have to count for each row the number of rows in the table depending on filter of the sorted field and also depending on filters of few other fields. I could solve this problem with COUNTIFS function, but there is another condition. One of the "fileds - filter" must be distinct, the others may be duplicates too.

?

Any help would be much appreciated!

Many thanks,

Ivan

Hi I want to count values excluding the duplicates.

For example, I have two materials with different batch numbers for each material which contains 10 containers each belonging to multiple shipping lines. from this 20 containers of two batches, I want to count no. of containers under each shipping lines by using countifs and criterias are material name, batch number and shipping line and type of container (20' or 40'). Each containers weighs 24.75 tons but I have one container 12.375 in first batch and 12.375 in another batch. I don't want this container to be counted twice when I enter the batch number.

Hi, I wish to all af you nice & new challanges, for 2017.

I have my own and asking for your help... My data are as below, in Excel 2013:

-column A: incomming invoice date (can be more identical, as there are more invoices on the same day). Like jan01, jan01, jan02, jan15, jan15, ...

The column is filtered, / Month or whatever.

I need to count the dates where there is only one input (row) in the filtered range (needed result is 1 (jan02) from above example, as that is the day when just one invoise was received.

There is no option to add more columns. Is it possible to get the right result by using the date column only?

Thanks and looking forward to your advice.

How would I count distinct dates in a selection of cells? I tried changing the dates to number format and then using =SUM(IF(ISNUMBER(range),1/COUNTIF(range, range),"")), but I got an incorrect answer with an error saying that the formula "omits adjacent cells".

Hi,

I forgot to select Add this data to the Data Model checkbox.what to do now

First - thank you so much for this site. Very helpful.

I have a spreadsheet with a large number of distinct account numbers. Each time an account number appears on the spreadsheet, whether duplicate or unique, it represents a different transaction with a value for each transaction. There are 3 columns, (A) for acct. #; (B) for transaction 1; and (C) for interest on transaction 1. I would like to get a list of distinct account numbers with the sum of the values for each distinct acct. number. (At the end, the list would contain a column for: (A) Distinct Acct.#; and, (B) sum or total transaction value for all values for each acct#; and (C) total or sum of interest for each acct#.

Hello Paul,

Thank you very much for your feedback, we're happy to hear you find our site helpful.

It sounds like the Subtotal option in Excel will do what you need:

- Select your records and go to Data tab

- Click on Subtotal and choose the following options:

- At each change in - column with the account number, use function - SUM, add subtotal to - select the columns with the values you want to sum.

- Click OK

I hope this helps.

Yes - absolutely worked. Wonderful. Thank you!!

my inputs are

Abc 2 500

def 1 2000

abc 4 300

Output should be:

Abc 6 800

def 1 2000

Hi,

I have an excel sheet for training records which has columns named "name of course", "instructor", "course number", "attendee", "duration"etc. As I have multiple attendees on each training, training number is remaining same for different attendees. I would like to see the total duration for each instructor seperately on pivot table however, when I use "sum of duration" as a pivot table column, it is calculating all the numbers shown under duration column. (I mean, if there are 5 attendees for same training and if the duration is 8 hours, value that I want to see on pivot table is 8 hours, unfortunately it multiplies the number of attendees and duration and seems 40 hours) Is there a way to solve this problem?

Thanks in advance.

Thank you! It helped a lot!

I have pulled data from several states with account, I want to look at only one state & only count unique Business in that state, no duplicates

Hello

I am a teacher trying to use google sheets to gather data. I'd like to break each assessment question into two parts: one for understanding the concept, and the other for computation. The only value that will go in each will be an x indicating that there was an error. I then want to accumulate separate totals based on these entries. Because this same rule doesn't apply to every question, not all questions will have a concept and computation part.

I am trying to use COUNTIF as follows:

COUNTIF(C7,"x")+(G7,"x")+(I7,"x") etc. I am getting a Formula parse error in the cell.

Any help you can give is appreciated!
