Find Duplicate Rows
In the previous post, we talked that how to highlight duplicate rows with conditional formatting feature in excel. And this post will teach you how to find duplicate rows with an excel formula.
If you want to check the entire row that duplicated or not, if True, then returns “duplicates” value, otherwise, returns “no duplicates”. How to achieve it? You can create a formula based on the IF function and the SUMPRODUCT function.
Assuming that you want to find or check duplicate rows in range A2:C6, then you can write down the following formula:
=IF(SUMPRODUCT(($A$2:$A$6=A2)*1,($B$2:$B$6=B2)*1,($C$2:$C$6=C2)*1)>1,"duplicates","No duplicates")
You can enter the above formula into the formula box in Cell D2, then press Enter. You will see that if there are same rows in the range, it will display “duplicates”, or it will display “No duplicates”.
Last, you can drag the AutoFill Handle down to the rest cells in Column D to check duplicate rows.
