Frequently asked questions
What does Microsoft's Spreadsheet Compare offer that this tool doesn't?+
Spreadsheet Compare also diffs VBA code and formatted reports with a two-pane side-by-side view. This tool focuses on cell value and formula diffs with a downloadable report.
Can I use this with .xls (older Excel) files?+
SheetJS reads .xls files. Upload .xls as you would .xlsx — the comparison works on both formats.
Does it detect changes in sheet names between versions?+
Sheet name changes result in unmatched sheets (one present only in A, one only in B). All cells in each are marked as added/removed.
