Once published, this detector set version is not silently edited. Detector additions, removals, severity changes, and verdict-policy changes require a new detector set version.

Included detectors

Issue typeSeverityWhat it checks
broken_reference error Flags active formula failures such as #REF! outputs and lookup formulas that request a column or row outside the referenced range.
visible_formula_error error Flags formula cells returning visible error values: #N/A, #VALUE!, #DIV/0!, #NAME?, #NUM!, #NULL!, or #ERROR!. Literal text values are not flagged.
mixed_text_number warning Flags columns that mix numeric and text-stored values, a common source of silent SUMIFS, COUNTIFS, and AVERAGEIFS mistakes.
duplicate_lookup_key warning Flags lookup-key columns with duplicate values when used by VLOOKUP or XLOOKUP, because those formulas silently return the first matching row.

Verdict thresholds

Informational findings do not affect the verdict in v0.2.

Scope limits

Detector Set v0.2 evaluates the bounded data sent to the SheetBrain backend for the audit. Public reports describe this as data cells evaluated (headers excluded).

  • Maximum evaluated rows per sheet: 1,000 data rows.
  • Maximum evaluated columns per sheet: 50 columns.
  • Headers are used for context but are not counted as evaluated data cells.
  • The scan evaluates the workbook snapshot sent at audit-generation time, not future changes.

Limitations

  • Does not verify source data accuracy, completeness, authorization, or business assumptions.
  • Does not certify that a spreadsheet is suitable for a specific legal, tax, audit, investment, or procurement decision.
  • Does not validate external data sources, API integrations, named-range references outside the evaluated scope, or third-party add-on output.
  • Does not detect formula drift after a column move or rename. SheetBrain Repair handles that separately with a schema snapshot and AI-assisted rewrites.

v0.2 changelog

  • Added visible_formula_error as an error detector for formula cells returning #N/A, #VALUE!, #DIV/0!, #NAME?, #NUM!, #NULL!, or #ERROR!.
  • Kept #REF! under broken_reference to preserve the more specific broken-reference explanation and lookup-index auto-fix behavior.
  • Kept verdict thresholds, scope limits, report schema version, and Standard version unchanged from v0.1.
