Useful Excel macro will compare rows in 2 lists of data based on 1 to 3 columns in each list.

Creates a new spreadsheet with matched rows from original 2 lists merged together on the same row and unmatched rows highlighted on separate rows.

As the 2 lists of data are merged into a one spreadsheet, the number of columns of the 2 lists together must not exceed the maximum number of columns Excel supports. Tested on MS Office 97 - XP.

Requirements:

· MS Excel 97 or higher
