Excel Workbook QA Pro

Audit Excel workbooks before you trust, send, or deliver them.

Excel Workbook QA Pro performs a non-destructive quality-assurance audit of .xlsx and .xlsm workbooks and returns traceable findings without modifying the original file.

What it checks

The V1 engine runs 38 controls covering:

• workbook integrity and preflight checks;
• hidden sheets, rows, columns and structural risks;
• broken formulas and references;
• possible hard-coded values inside formula series;
• missing or inconsistent formulas;
• external workbook links and data connections;
• circular references detectable statically;
• numbers stored as text;
• duplicate records;
• inconsistent data types;
• unexpected blanks;
• numeric and date outliers;
• Excel data-validation violations;
• formula consistency across similar worksheets;
• suspicious SUM-range omissions;
• workbook calculation and dependency risks.

Evidence-based findings

Each finding includes:

• worksheet and cell/range location;
• severity;
• confidence level;
• evidence type;
• affected cells;
• recommended review action.

The engine distinguishes direct technical evidence from heuristic findings. Pattern-based findings are never presented as certain facts.

Outputs

Each completed audit can generate:

• a concise QA summary;
• an HTML QA report;
• an Excel findings register;
• a machine-readable JSON report.

Safety

• The original workbook is never overwritten or repaired.
• VBA macros are never executed.
• External links and data connections are never refreshed.
• Microsoft Excel is not used to recalculate formulas.
• The tool does not claim to validate the truth of the underlying business data.

Supported files

V1 supports .xlsx and .xlsm.

Password-encrypted, corrupt, unsupported, suspicious, or excessively large workbooks may be rejected or only partially analyzed.

Important limitation

The QA score is a structured risk indicator, not a certification that a workbook is error-free or suitable for every business purpose. Important findings should be reviewed before operational, accounting, financial, legal, or other high-impact decisions.
