Find duplicate using COUNTIF Function
Using the COUNTIF function helps us:
- Find only the duplicate values, and
- Count how many times the value is repeated in the list.
So let’s find out a duplicate with Countif Function in Excel

Now let see how CountIF calculates the number of repetition.
1. Now in Column B we will count each name repetition. In cell B1 type the name of Column Count as like above picture. Now use below formula in cell B2 for count the number of repetition of the name John in cell A2:
=COUNTIF( A:A, A2 )
2. This formula is telling to count the repeated number of the value of cell A2 in the range of A:A (means the whole column of A).

Now we can see in cell B2, it counts that name John is entered only 1 time. So now let input the same formula into other cells of column B.

3. Using the Fill handle of the selected cell. Click, hold, and drag it below another cell of column B as like the above picture. The formula will be copied automatically for other cells of column B.
