The Spreadsheet Professional add in allows you to focus on Spreadsheet Change Control by showing differences in inputs and formula
Spreadsheet Change Control
If you create multiple versions of spreadsheets, it is difficult to know exactly what has changed from one version to the next. The comparison tool allows you to implement spreadsheet change control allowing you to identify differences in inputs, formulas or results in different versions of the same spreadsheet.
This feature is available in the Spreadsheet Professional tool
