How Excel Formula Diff works

ExactDiff extracts formula text and cell addresses from each worksheet, then compares the formula map without relying on cached display values.

The comparison is deterministic: the same files and settings produce the same classification. File contents remain inside the current browser session.

  1. 01Use workbooks saved as XLSX.
  2. 02Review removed formulas before changed formulas.
  3. 03Confirm intentional absolute and relative reference changes.
