SheetSense detects formula inconsistencies, silent overwrites, and structural issues in real time — the problems spreadsheets never show you.

SheetSense runs 15+ rule-based checks that catch the mistakes humans miss — all without sending your data anywhere.
If 99 rows use a SUM formula but one row is a hardcoded number, SheetSense catches it instantly.
When someone accidentally types over a formula, replacing it with a static value, you'll know immediately.
Every sheet gets a 0-100 health score with a breakdown by severity. Know at a glance if your data is trustworthy.
Text in a number column silently breaks SUM and AVERAGE. SheetSense finds every type mismatch.
Cells referenced by 10+ formulas are flagged as high-impact. One accidental edit could cascade errors everywhere.
Mega-formulas, magic numbers, and circular references get flagged with clear suggestions to simplify.
