You are short on details but.............................

The add-in, Compare.xla written by Myrna Larson and Bill Manville, allows
you to compare the contents of two workbooks and highlight differences.

Download Compare.ZIP, unzip Compare.xla and add it with rest of your your
add-ins.

On Tools Menu, select add-ins and check in (tick in)Compare Worksheets.
From tools menu then select Compare Sheets and follow instructions.
