*The tutorial looks at how to leverage the new dynamic array functions to count unique values in Excel: formula to count unique entries in a column, with multiple criteria, ignoring blanks, and more.*

A couple of years ago, we discussed various ways to count unique and distinct values in Excel. But like any other software program, Microsoft Excel continuously evolves, and new features appear with almost every release. Today, we will look at how counting unique values in Excel can be done with the recently introduced dynamic array functions. If you have not used any of these functions yet, you will be amazed to see how much simpler the formulas become in terms of building and convenience to use.

Note. All the formulas discussed in this tutorial rely on the UNIQUE function, which is only available in Excel 365 and Excel 2021. If you are using Excel 2019, Excel 2016 or earlier, please check out this article for solutions.

## Count unique values in column

The easiest way to count unique values in a column is to use the UNIQUE function together with the COUNTA function:

*range*))

The formula works with this simple logic: UNIQUE returns an array of unique entries, and COUNTA counts all the elements of the array.

As an example, let's count unique names in the range B2:B10:

`=COUNTA(UNIQUE(B2:B10))`

The formula tells us that there are 5 different names in the winners list:

Tip. In this example, we count unique text values, but you can use this formula for other data types too including numbers, dates, times, etc.

## Count unique values that occur just once

In the previous example, we counted all the different (distinct) entries in a column. This time, we want to know the number of unique records that **occur only once**. To have it done, build your formula in this way:

To get a list of one-time occurrences, set the 3rd argument of UNIQUE to TRUE:

`UNIQUE(B2:B10,,TRUE))`

To count the unique one-time occurrences, nest UNIQUE in the ROW function:

`ROWS(UNIQUE(B2:B10,,TRUE))`

Please note that COUNTA won't work in this case because it counts all non-blank cells, including error values. So, if no results are found, UNIQUE would return an error, and COUNTA would count it as 1, which is wrong!

To handle possible errors, wrap the IFERROR function around your formula and instruct it to output 0 if any error occurs:

`=IFERROR(ROWS(UNIQUE(B2:B10,,TRUE)), 0)`

As the result, you get a count based on the database concept of unique:

## Count unique rows in Excel

Now that you know how to count unique cells in a column, any idea on how to find the number of unique rows?

Here's the solution:

*range*))

The trick is to "feed" the entire range to UNIQUE so that it finds the unique combinations of values in multiple columns. After that, you simply enclose the formula in the ROWS function to calculate the number of rows.

For example, to count the unique rows in the range A2:C10, we use this formula:

`=ROWS(UNIQUE(A2:C10))`

## Count unique entries ignoring blank cells

To count unique values in Excel ignoring blanks, employ the FILTER function to filter out empty cells, and then warp it in the already familiar COUNTA UNIQUE formula:

*range*,

*range*<>"")))

With the source data in B2:B11, the formula takes this form:

`=COUNTA(UNIQUE(FILTER(B2:B11, B2:B11<>"")))`

The screenshot below shows the result:

## Count unique values with criteria

To extract unique values based on certain criteria, you again use the UNIQUE and FILTER functions together as explained in this example. And then, you use the ROWS function to count unique entries and IFERROR to trap all kinds of errors and replace them with 0:

*range*,

*criteria_range*=

*criteria*))), 0)

For example, to find how many different winners there are in a specific sport, use this formula:

`=IFERROR(ROWS(UNIQUE(FILTER(A2:A10,B2:B10=E1))), 0)`

Where A2:A10 is a range to search for unique names (*range*), B2:B10 are the sports in which the winners compete (*criteria_range*), and E1 is the sport of interest (*criteria*).

## Count unique values with multiple criteria

The formula for counting unique values based on multiple criteria is pretty much similar to the above example, though the criteria are constructed a bit differently:

*range*, (

*criteria_range1*=

*criteria1*) * (

*criteria_range2*=

*criteria2*)))), 0)

Those who are curious to know the inner mechanics, can find the explanation of the formula's logic here: Find unique values based on multiple criteria.

In this example, we are going to find out how many different winners there are in a specific sport in F1 (*criteria 1*) and under the age in F2 (*criteria 2*). For this, we are using this formula:

`=IFERROR(ROWS(UNIQUE(FILTER(A2:A10, (B2:B10=F1) * (C2:C10<F2)))), 0)`

Where A2:B10 is the list of names (*range*), C2:C10 are sports (*criteria_range 1*) and D2:D10 are ages (*criteria_range 2*).

That's how to count unique values in Excel with the new dynamic array functions. I am sure you appreciate how much simpler all the solutions become. Anyway, thank you for reading and hope to see you on our blog next week!

Hi! Sorry, it's not quite clear what you are trying to achieve. The example of results don't match your questions. Maybe this article will be helpful: Get a list of unique values in Excel.

Hi,

I am looking to count the number of unique species by their phyla in 3 different locations. I have a sheet with three columns: site, species, and phyla. The sites are A, B, and C. Species can be grouped into phyla. I am looking for a formula that can produce the number of unique species in each phyla category per site so that I can compare species richness across sites and make graphs that are color coded by phyla.

Trying the method described in the "Count unique values with multiple criteria" section produces an error. Seems like the error is with FILTER as that doesn't work by itself.

Here's an example of the sheet for visualization, but it is many thousands of rows in actuality. :)

site species phyla

A dalli arthropoda

A dalli arthropoda

A chondra rhodophyta

A caula rhodophyta

B dalli arthropoda

B glandula arthropoda

B egregia ochrophyta

B chondra rhodophyta

C dalli arthropoda

C egregia ochrophyta

C silvetia ochrophyta

C caula rhodophyta

Hi! I don't know what is not working for you, as you haven't written your formula. Use the recommendations from the article above and try this formula for an example:

=COUNTA(UNIQUE(FILTER(B2:B13,(C2:C13="arthropoda")*(A2:A13="A"))))

Hi! Pay attention to the following paragraph of the article above – Count unique values with criteria.

It covers your case completely.

HI,

I have a Calculator worksheet that pulls the following from another worksheet in the workbook:

=COUNTIF('test page Cost Centers'!F:F,TRUE).

This is used to divide an invoice amt between certain providers by suite # (F:F)

Here are the column headings for the Calculator worksheet.

A B C D E F G J

Subtotl Tax Suite Specialty SubAcct #CostCtr ProviderCode Provider Name

The 'test page Cost Centers" worksheet has the following formula:

=C3=Calculator!$C$6

Here are the column headings for the Cost Center worksheet.

A B C D E F G

cost ctr Provider Suite Specialty (null) Match C Match D

How do I change the COUNTIF formula to count either the suite#(F:F) and/or the Specialty(D:D) when muliple specialty are in the same suite#?

I get a little confused with the unique values statement but think this is something needed to pull the numbers I need.

Thank you for your time.

Hi! To do counting on multiple conditions, use the COUNTIFS function. Here is the article that may be helpful to you: Excel COUNTIFS and COUNTIF with multiple AND / OR criteria. I hope it’ll be helpful.

Hi Sir, I have 3 columns of below:

Column A Column B Column C

20/7/2023 2023-07 Pizza Hut

21/7/2023 2023-07 KFC

22/8/2023 2023-08 Pizza Hut

23/8/2023 2023-08 KFC

24/8/2023 2023-08 Pizza Hut

25/8/2023 2023-08 KFC

I have used below formula to get the figure of count of KFC in 2023-08, but only get answer = 1

=IFERROR(ROWS(UNIQUE(FILTER($C:$C,($B:$B="2023-08")*($C:$C="KFC")))),0)

How to slot in the criteria with date (Column A) inside the formula to get answer =2 ?

Hi! Use column A to count unique values. Modify the formula:

=IFERROR(ROWS(UNIQUE(FILTER($A:$A,($B:$B="2023-08")*($C:$C="KFC")))),0)

Hi I would like to know how to count number of unique values that meets either of the criteria.

Taking the above example in “ Count unique values with criteria”, I want to count the total number of winners in basketball and volleyball.

May I know if there is a formula for such case? Thanks

Hi! To count the number of unique values by OR condition, use + (sum) instead of * (multiplication) in the formula. For example,

=IFERROR(ROWS(UNIQUE(FILTER(A2:A10, (B2:B10=F1) + (B2:B10=G1)))), 0)

Hi there,

I have 4 collumns

I have a table with values between rows 2 and 57, and between collumns C to F.

I want to count how many times in the whole table: Collumn C contains the text "On-Call" and the Collumn D OR Collumn E OR Collumn F text on the same row contains the text "Bank Holiday".

I can understand how I would do this if the intended logic was "and" where "or" is, but I cant figure out how to get it to work as I've written.

I've tried:

=COUNTIFS(C2:C57, "On-Call", OR(D2:D57="Bank Holiday",E2:E57="Bank Holiday",F2:F57="Bank Holiday"),"TRUE")

which didn't work.

Thanks!

Hi! The answer to your question can be found in this article: Count cells with multiple criteria (OR logic). For example,

=COUNTIFS(C2:C57, "On-Call", D2:D57,"Bank Holiday") + COUNTIFS(C2:C57, "On-Call", E2:E57, "Bank Holiday")

But wouldn't that count it twice? I'm after an "or" (not exclusive) not an "and" relationship between the contents of collumns D E and F. I want it to return a value of 1 if Collumn C contains "On-Call" and at least one (but potentially up to all 3) of collumns D E and F contain "Bank Holiday"

Hi! Try to use SUMPRODUCT function:

=SUMPRODUCT(--(C2:C20="On-call"),--(((E2:E20="Bank Holiday")+(F2:F20="Bank Holiday"))>0))

Hope this is what you need.

Hi,

Is there a way to use SPILL in a FILTER formula?

I've got a SPILL list of Unique locations.

=SORT(UNIQUE(TablePrint[Location]))

Secondly I want to show a dynamic list of Unique CaseID's for the locations.

=ROWS(UNIQUE(FILTER(TablePrint[Case ID];TablePrint[Location]=AO6)))

This works fine, but I have to fill the series manually to the same size as the first SPILL list.

I need to get that dynamically.

The Cell reference 'AO6' references to the first cell of the UNIQUE SPILL list of the first formula.

If I change this reference to 'AO6#' it give's a "#N/A".

I'm out of thoughts, so any help will be appreciated.

Hi! To extract the first value from an array of unique values, use the CHOOSEROWS function.

CHOOSEROWS(AO6,1)

I hope it’ll be helpful.

Hi, I have employee codes in column A, and their Gender in column B.

1234 Female

5678 Male

9101 Female

1213 Male

1234 Female

I want the count of females, excluding the duplicate values. For example, in the above table, the count of females should show 2 (Instead of 3) since 1234 is a duplicate value.

Hi! Pay attention to the following paragraph of the article above: Count unique values with criteria.

It covers your case completely.

Yes, it worked!

Please can you also help with the below

1234 Female United Kingdom

5678 Male Ireland

9101 Female United Kingdom

1213 Male Russia

1234 Female United Kingdom

Need the overall count of UK and Ireland employees excluding duplicates.

The formula I used: =IFERROR(ROWS(UNIQUE(FILTER(M643:M662,AF643:AF662="United Kingdom","Ireland"))),0)

It did not work. The above one is only pulling the count of United Kingdom. Please help

Hi! Using your data, the formula for calculating unique values by condition can be like this:

=IFERROR(ROWS(UNIQUE(FILTER(A1:C5,(C1:C5="United Kingdom")+(C1:C5="Ireland")))),0)

I recommend reading this guide: Excel FILTER function - dynamic filtering with formulas.

Thanks

Hi!

Unfortunately, I don't understand what you want to do. Give an example of the result.

Hi there,

I have been using this on a MacBook and I cannot get the command to work. I have a list of companies, which I cannot share due to confedeniality, but an overview is similar to this:

Company A - Acquisition 1 - USA

Company A - Acquisition 2 - USA

Company A - Acquisition 3 - France

Company B - Acquisition 1 - UK

Company B - Acquisition 2 - USA

Company B - Acquisition 3 - Japan

Company C - Acquisition 1 - USA

Company C - Acquisition 2 - China

Company C - Acquisition 3 - France

Company C - Acquisition 1 - Germany

Company C - Acquisition 2 - China

Company C - Acquisition 3 - China

So I want to count the number of countries that are acquired per Company but when I run the IFERROR(ROWS(UNIQUE(FILTER...) command every one comes out as zero. I ran it before and it worked fine but I cannot figure out if I am doing something wrong.

Thanks!

Hi!

I can't give advice on a formula that I don't see. Think about what has changed in your data.

Hi!

My apologies - I am relatively new to these forums and to data analyses within excel, so I am sorry for not giving the formula!

If the company names are in column A, and the countries in column C, then I am using =IFERROR(ROWS(UNIQUE(filter($C$2:$C$17220,$A$2:$A$17220=A2))),0)

I get the value of 0 for every row and cannot understand what I am doing wrong! Apologies for my ignorance if it is something obvious. I very very much appreciate any help you have to offer!

Thanks,

Dee

Hi!

Your formula works for me. There may be a problem with the version of Excel. Try the formula without IFERROR and you will see where the error is.

=ROWS(UNIQUE(FILTER($C$2:$C$17220,$A$2:$A$17220=A2)))

Hi Ablebits Team, thank you for this post, this formula have saved me a lot of time and kudos for giving me new knowledge for my work.

I do have a question, in using the same data in your article, example on taking how many win for Basketball and under age 18 that use the below formula:

=IFERROR(ROWS(UNIQUE(FILTER(A2:A10, (B2:B10=F1) * (C2:C10<F2)))), 0)

how do I then extend this formula to see how many win for Basketball and Hockey under age 18 for example? I try part of the formula (B2:B10=AND("Basketball","Hockey")) in excel it doesn't work. Could you advise the best formula I can use for this issue?

Right now on my work I have similar issue on my data and I can't be able to find the best formula to count multiple criteria under the same column as above. Thank you in advance for your help!

Hi!

If you write the second criterion in cell G1, then add the second condition to the formula:

=IFERROR(ROWS(UNIQUE(FILTER(A2:A10, ((B2:B10=F1)+(B2:B10=G1)) * (C2:C10 < F2)))), 0)

See examples here: Filter based on AND as well OR criteria.

Hi,

I have a data of meetings which is datewise which is bifurcated week wise and month wise and then in house, video call and outdoor meetings. I want to pull the summary of this data like how many meetings are done per week unique, inhouse and outdoor.

I could extract the summary using countifs but cant find the unique fields. can you please help

Hi!

I don't see your data and I don't understand why you can't use the COUNTIFS function. Look for the example formulas here: Excel COUNTIFS and COUNTIF with multiple AND / OR criteria.

Also you can use SUMPRODUCT function to conditionally count cells with multiple criteria.

If this is not what you wanted, please describe the problem in more detail.

Hi Good day,

Column A Column B Column C

A AA XX

A AA XX

A AA XX

A AB YY

A AB XX

B BB XX

B BB XX

B BC YY

B BC XX

B BC ZZ

From the sample data above, I want to count how many distinct text in column C that group by column A)and column B. The result I wish to get is like this:

Column A Column B Column C

A AA XX 1

A AA XX 1

A AA XX 1

A AB YY 2

A AB XX 2

B BB XX 1

B BB XX 1

B BC YY 3

B BC XX 3

B BC ZZ 3

For group A, AA only XX in the group show 1 for each row, For group B,BC there are YY, XX and ZZ in it so show 3 for each of them.

I've tried using this formula =

SUM(--(FREQUENCY(IF($A$2:A2=A2,MATCH($C$2:C2,$C$2:$C2,0)),ROW($C$2:C2)-ROW(D2)+1)>0))

but I didn't get what I want T.T

Hope you understand my question. Thanks in advance for helping.

Hello!

Try to use the recommendations described in this article: Count unique values with multiple criteria.

If I understand your task correctly, the following formula should work for you:

=IFERROR(ROWS(UNIQUE(FILTER($C$1:$C$10, ($A$1:$A$10=A1) * ($B$1:$B$10=B1)))), 0)

You can copy this formula down along the column.

Thank you so much for reply.

Sorry, forgot to tell. I'm using Microsoft Excel 2010 and it don't have function UNIQUE and FILTER. Is there any functions suitable for Microsoft Excel 2010 in this situation?

Hi!

Unfortunately, I do not know of a way to solve this problem with your Excel version.

Hello,

I want to count what is the number of rooms based on the date entered and cell colour. If there is no date entered, I don't want it to be counted. The rooms is arranged in multiple rows and column.

As example, the total number of blue cells is 458. In that 458, 110 cells have date meanwhile the rest is empty. So, how do I write formula for this as I am dealing with multiple colours as well.

Hello!

To count the number of cells with a specific color, you can use the user-defined function CountCellsByColor. You can find the examples and detailed instructions here: How to count and sum cells by color in Excel.

You can define empty cells with the ISBLANK function.

I hope this will help, otherwise don't hesitate to ask.

Hi, I'm trying to count unique values with multiple criteria but nothing seems to fit what I need.

I have a sheet with data and a sheet with results within the same book.

In a cell on the results sheet I am trying to count the number of unique items (job number) on the data sheet that match two sets of criteria, because the same criteria could have multiple lines under the same job number (for different months).

Eg on the data sheet:

Job# Month Customer Status

123 Jan Joe's jugs Closed

123 Feb Joe's jugs Closed

124 Jan Joe's lamps Open

125 Feb Jim's tables Closed

126 Feb Joe's pots Closed

I'm looking for the number of jobs on any account that belongs to Joe (so using a wildcard that Sumproduct can't handle) that are closed, but with unique job numbers (due to the spillover of job into other months). ie I'm trying to get a formula to give me a result of 2 [job 123 and 126], but can't find anything that works. Closest I've come is COUNTIFS, but I can't remove the duplicate job numbers so it will give me 3 [job 123 twice plus 126]. If I try to incorporate UNIQUE into that I get a SPILL error.

Hi!

Please re-check the article above since it covers your task.

Here is the formula for your task:

=COUNT(UNIQUE(FILTER(A2:A6,(C2:C6="Joe’s")*(E2:E6="Closed"))))

Hello -
