## How to count duplicate values in a column in Excel?

In the realm of data analysis and management, identifying and counting duplicate values in a dataset is a crucial task. Excel, provides several methods to count duplicate values in a column efficiently. This article explores various techniques to accomplish this, from simple functions to more advanced features, helping you choose the best approach based on your dataset size and specific requirements.

For example, if you have a list of data in a worksheet containing both unique and duplicate values, you may not only want to count the frequency of these duplicates but also determine the order of their occurrences as following screenshot shown.

#### 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).

#### Track the order of occurrence of duplicates in Excel

But if you want to identify the order of the occurrence of the duplicates, you can use the following formula.

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

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")
