Compare Microsoft Excel spreadsheets easily, with Spreadsheet Compare add-in
Spreadsheet Compare is a free Microsoft Excel add-in you can use to compare pairs of spreadsheets.
The program lets you select particular spreasheets in workbooks and criteria according to which they will be compared. The program locates and presents their differences.
Note that Spreadsheet Compare may modify source files; it would be wise if you compared copies of your files and not the files themselves. Spreadsheet Compare can merge differences in a new workbook that it creates for this purpose.
As most Office add-ins Spreadsheet Compare is not perfect, but it’s a nice tool you may like to try if you are interested in spreadsheets comparisons.
