The VLOOKUP function can look up and bring data from a specific column. So here, you can use the VLOOKUP function to compare two columns in Excel for matches. Here are the steps to do it.

1. First, you need to insert a new column next to the second column you want to compare.
2. In the first cell, you will enter the VLOOKUP formula such as =VLOOKUP(cell reference, range of cells, column number, FALSE)
3. You should select or write cell reference with the first cell.
4. Then, you will choose entire range of cells in the second column for comparing as second element.

Note: When comparing Excel columns, the cells’ order matters tough. In other words, if the cells in the two columns are not in the same order, these methods may not identify matches. Hence, you need to sort the columns in the same order first.
