When you'd use this
- Auditing a spreadsheet's formulas for anything that recalculates unexpectedly
- Checking for formulas that depend on another, external workbook
- Reviewing a complex workbook's logic before relying on it
Shared formulas (one formula definition reused across a range of cells) are shown at their base cell; this tool doesn’t currently re-derive the translated formula for every cell that shares it.
