Detect formula errors, silent overwrites, and structural issues in Google Sheets and Excel Online in real time. 88% of spreadsheets contain errors. Is yours one of them? SheetSense is a Chrome extension that detects hidden errors in your Google Sheets and Excel Online spreadsheets — the problems your spreadsheet never shows you. Click "Scan Sheet" and get a complete health report in under 3 seconds. No data leaves your browser. 🔍 WHAT SHEETSENSE DETECTS ▸ Formula Inconsistencies — If 99 rows use SUM but one row has a hardcoded number, SheetSense catches it instantly. ▸ Silent Overwrites — When someone accidentally types over a formula and replaces it with a static value, you'll know immediately. ▸ #REF!, #DIV/0!, #NAME? Errors — Every broken formula reference is flagged with a clear explanation and fix suggestion. ▸ Circular References — Self-referencing formulas that can break your entire sheet. ▸ Mixed Data Types — Text in a number column silently breaks SUM and AVERAGE. SheetSense finds every mismatch. ▸ Data Gaps — Empty rows in the middle of your data that break formulas assuming contiguous ranges. ▸ Critical Input Cells — Cells referenced by 10+ formulas are flagged as high-impact. One accidental edit could cascade errors everywhere. ▸ Complex Formula Warnings — Mega-formulas and magic numbers get flagged with suggestions to simplify. ▸ Duplicate Headers — Column headers that repeat and can break VLOOKUP/INDEX-MATCH. 📊 HEALTH SCORE Every scan produces a 0-100 health score with letter grade (A through F) and a breakdown by severity — Critical, High, Medium, and Low.
