matching columns

[Ghanima2012]

I have two columns with numbers. One column has numbers that the other column does not have. I would like to find all the numbers that are in the one column and not the other and delete them. Thanks!

Hi, I'm struggling to know what you want to do? It sounds like you want to compare both columns against each other and delete duplicates? But the quote, one column has numbers that the other does not have. I would like to find all the numbers that are in column one and not the other and delete them is confusing!!! Possibly post a sample workbook of before and after results. Thanks
