If you want to count duplicates or unique values in a certain row rather than a column, use one of the below formulas. These formulas might be helpful, say, to analyze the lottery draw history. Count duplicates in a row: =SUMPRODUCT((COUNTIF(A2:I2,A2:I2)>1)*(A2:I2<>"")) Count...
Example 21 – Using COUNTIF and SUMPRODUCT to Count Duplicates Between Two Columns We have a dataset of twoNamelists. Insert the following formula in the cell where you want the result, then hit Enter. =SUMPRODUCT((COUNTIF(B4:B13,C4:C13)=0)*(C4:C13<>"")) The COUNTIF function checks ...

You can count duplicates of a value in a specific range with the COUNTIF() function. For example =COUNTIF(A2:A10, A2) will show you the count of duplicate values in the specified range. If you want to learn how to find unique values too, check out our article on How to Count Uni...
The image above shows example data in cell range B6:B20, it contains random fruits, some are duplicates, some are unique. The array shown in cell range C6:C20 corresponds to the same item in B6:B20 meaning the number represents the count/frequency of that particular value. For example, th...

Another way to count cells with OR logic in Excel is to use theSUMPRODUCT functionin this way: SUMPRODUCT(1*(range={criterion1,criterion2,criterion3, …})) To better visualize the logic, this could also be written as: SUMPRODUCT((range=criterion1) + (range=criterion2) + …) ...
