Florencesoft™ DiffEngineX™ - Compares Excel Worksheets
Difference (Diff) & Row/Column Alignment Utility for Microsoft® Excel on Windows platforms
Free To Use for the First 30 Days

DiffEngineX is a fast utility that finds the differences between the formulae, constants, defined names, cell comments and Visual Basic code contained in either two whole Excel workbooks or selected worksheets. It generates a cell-by-cell difference report in a new workbook and color highlights different cells in automatically made copies of your workbooks.
As Excel spreadsheets get modified over time new rows and columns can be inserted between existing ones. DiffEngineX can align both similar rows and columns.
It has many powerful features such as the ability to hide matching rows, group like changes to adjacent cells and highlight differences at the character level. It can be used from its user interface or programmatically using command-line arguments.
By reporting the differences between original and modified Excel files, it has a role in version control and management.
