Excel Formulas Not Calculating
Diagnose formulas that show old values, text, or unexpected results.
What this solves
Fix a workbook that stopped updating after an import. This pattern is useful when the business question is clear but a generic tutorial is too abstract.
The rule
Check calculation mode, text-formatted cells, leading apostrophes and circular references.
Formulas → Calculation Options → AutomaticGoogle Sheets: The core pattern is also usable in Google Sheets; exact function support and locale separators can differ.
Real-work checklist
- Define the business key and expected grain before writing the formula, query or markup.
- Test the pattern on a small known sample where you can verify the answer manually.
- Check missing values, duplicates and data types before trusting a large result.
- Scale to the real file or database only after the logic is proven.
Common mistake
Re-entering formulas may hide the root cause; identify why calculation stopped first.
