What changed in my spreadsheet?
Updated August 30, 2026
Quick answer
To find what changed in a spreadsheet, compare the new file against the last approved version and scan for formula edits first, then values, formatting, added sheets, and embedded charts or images. A visual diff tool groups changes by type so you do not miss structural edits hidden outside the grid.
Where should I start when reviewing spreadsheet changes?
A good diff tool groups edits by cell, sheet, and change type. Scan for unexpected sheets first — added tabs often hide new assumptions.
Why check formulas before cell values?
Value shifts may be correct outputs of a broken formula. Filter for formula changes when reviewing models, tariffs, or tax calculations.
Do formatting changes matter if the numbers are unchanged?
Bold red totals can steer executives even when underlying numbers are unchanged. Style diffs matter in board packs.
What spreadsheet changes hide outside the grid?
Charts and embedded images carry narrative weight. Excel Change Log highlights those objects because they are easy to miss in CSV exports.
