Compare two Excel files
A coworker "just changed a few things" in your model. Which cells? Upload the older and newer version of the workbook and get a change report: formulas overwritten with typed values, edited formulas grouped by pattern (a re-dragged range is one change, not forty), new and resolved issues, and what it all did to the health score.
What the compare shows
- Hardcode overwrites — the killer signal: a cell that held a formula now holds a typed value (and the reverse). We even flag when the value equals the formula's last result — the classic silent paste-as-values.
- Formula changes, grouped — edits are normalized the same way our audit groups findings, so re-dragging a fill range reads as one change, not forty.
- Score delta — both versions get a full SheetScore audit: new criticals, resolved findings, and per-check score movement.
- Structure — added and removed sheets, named ranges, and cell regions, summarized by range.
Honesty note: cells are matched by sheet name and address. Inserting or deleting rows shifts everything below — when we see that pattern we label it a possible structural shift instead of listing a thousand "changes". A renamed sheet appears as removed + added.
A compare runs both files through the full audit and uses 2 audit runs from your quota (anonymous: 1 compare a day — free accounts get 5 audit runs a month, Pro 100 a day).
