How to count duplicate values in a column in Excel?

If you have a list of data in a worksheet with unique values and duplicate values, and you do not only want to count the frequency of duplicate values also want to know the order of the occurrence of the duplicate values. In Excel, the COUNTIF function can help you count the duplicate values.


Count the frequency of duplicates in Excel

In Excel, you can use COUNTIF function to count the duplicates.

Select a blank cell adjacent to the first data of your list, and type this formula =COUNTIF($A$2:$A$9, A2) (the range $A$2:$A$9 indicates the list of data, and A2 stands the cell you want to count the frequency, you can change them as you need), then press Enter, and drag the fill handle to fill the column you need. See screenshot:

Tip: If you want to count the duplicates in the whole Column, use this formula =COUNTIF(A:A, A2) (the Column A indicates column of data, and A2 stands the cell you want to count the frequency, you can change them as you need).

Hi Lia,
You can wrap multiple COUNTIF expressions into one SUM formula, in which the COUNTIF expressions shoule be seperated by comma. Here is an example: =SUM(COUNTIF($B$2:$B$8, B2),COUNTIF($B$2:$B$8, B3),COUNTIF($B$2:$B$8, B4)).The cells B2, B3, B4 stand for the value that you want to count its frequency.
Hope this helps you.

Hi, I'm trying to calculate the duplicate values as a single value in excel. But I can't. Can you help me?. For example, I have entered in rows as 1001,1002,1003,1004 and again 1001,1002,1003,1004" like this. In this case, all are duplicate ones. but it should bring "1001" as a single count, not two counts. Is there any formula for it?

Hi Manikandan.K,
Supposing the data you will count are placed in the Range A1:A20, you can use below arrow formula to count (a set of duplicates only count once):
=SUM(IF(A1:A20<>"",1/COUNTIF(A1:A20,A1:A20)))
Please note that it’s an array formula, please press Ctrl + Shift + Enter keys to get the counting result.

I have entered in a row as " 10,10,10,10,10,10,10,8,11,10,10,10,10,10" like this, now I entered 14 number values. How I can count the different number in single row? the result should be "14" in my case.

Hi Sampath Rangan,
Do you need to count all numbers in the row, or count the duplicates in the row?
Supposing the numbers are in the Range A1:N1, now you can count the numbers as follows:
Count all numbers: =COUNT(A1:N1)
Count duplicates, says 10: =COUNTIF($A$1:$N$1,"10")

I must be stupid as the KuTools solution is not working for me. I have copied the example with Fruits column (which I put 3 Apple entries in), made a column next to it which is blank called Count column. KuTools -> Content -> Advanced Combine Rows. Select Fruit column as primary key, Count column as Calculate -> Count. Hit OK. Nothing. No change to the sheet. Help please?

Dear, I am working on the attached Screenshot and Excel File. I need to calculate the Values in Column "G" i.e. to Count unique text values based on multiple (Two) criteria, but criteria are in NUMBERS. Further, Its is big sheet, therefore I want to use the cell reference in range and in criteria. I am very confused. I want to count the column C i.e. Degree based on the Criteria E and F. That is,I need to set formula in G2, such that, Look E2 in column A and Look F2 in column B and count the unique text values in Column C. Hope it is clear.

I am very thankful to you please


Details:
I have a data of more than 1000 companies with different year. As in column A, I have companies and B shows the year for which these companies have data. For example, First company have data for year 2011, 2012, 2013 and 2015. For company 2, I have data for year 2014 and 2011 and so on. Since majority of companies have data from 2011 to 2015, therefore I select this range in column F for each company. Now, I want to count the unique Degrees for cell G2, if there is 389841988 (Company ID for First company) in A and there is 2011 in Column B. Now I need to set formula in G2,in a way, If I will drag the formula G2 in cell G3, then It should give me the value by looking such as if there is 389841988 (Company ID for First company) in A and there is 2012 in Column B, the based on these two criteria, it should count the unique text in C2 and so on.
Look on the second sheet named Example, I did the same for INDEX, MATCH function and as well for SUMIFS function; in C2 I have the array formula INDEX($F:$H,MATCH(1,(A2=$F:$F)*(B2=$G:$G),0),3) and in D2 I have SUMIFS(I:I,F:F,A2,G:G,B2). These help me to do what I want with two criteria (To match and also to sum) and also I can drag these for rest of cell. I am looking something like this, or anything that I can drag to count unique degrees. Thank you very much. I am waiting.

Plz help. I am very thankful to for this kindness
