Frequently asked questions
Does it diff formula cells or just their values?+
Values and formula text are both compared. If two cells have different formulas but the same cached value, both differences are reported.
What if sheets were added or removed between versions?+
Sheets present in only one file are listed with all cells marked as fully added or fully removed.
Can it handle files where row or column order changed between versions?+
The diff is positional (same cell address). If rows were inserted or columns moved, the diff will show many spurious changes. Align the structure before comparing.
