Your spreadsheet has bugs you don't know about. SheetBrain scans for broken references, mixed data types, duplicate lookup keys, and
formula drift — in one click, unlimited, no AI call needed. It's the only Google Sheets™ add-on with deterministic error detection.

Type =SHEETBRAIN_HEALTH() in any cell to get an instant quality score. Run a full audit and share a public report link — no login
required for viewers. When columns move or get renamed, Schema Repair detects the drift and proposes batch formula rewrites so your
reports keep working.

Also generates formulas from plain English using your actual column headers. Explain any formula in plain English. Debug #REF!, #N/A,
and #VALUE! errors with context-aware fixes. Six custom functions work directly in the formula bar: =SHEETBRAIN, =AI_EXPLAIN,
=SHEETBRAIN_HEALTH, =SHEETBRAIN_ISSUES, =SHEETBRAIN_EXTRACT, =SHEETBRAIN_CLASSIFY.
