Find Duplicates with VLOOKUP or MATCH in Excel & Google Sheets

This tutorial will demonstrate how to find duplicate values using VLOOKUP and Match in Excel and Google Sheets.

Find Duplicate Values – VLOOKUP Function

To identify duplicate values in 2 columns in a range of cells in Excel you can use the VLOOKUP Function:

Find Duplicates VLOOKUP

If the cities are found in both columns B and C, then they will show in column D.

Find Duplicate Values – MATCH Function

Similarly, you can also find duplicate values in 2 columns using the MATCH Function.

Find Duplicates MATCH

The MATCH Function will return the row number if the duplicate exists, and a #N/A if the value is not duplicated.

Return Duplicate Value – the IF Function

If you want to return the duplicate value instead of the row number, you can expand the formula created by the MATCH Function to include an IF Function.
