Excel workbooks commonly drift after updates, with incorrect layouts, stale cached values, or hidden formula bugs. This Skill provides a structured verification flow that renders layouts, recomputes formulas, and analyzes formulas for semantic issues to ensure the workbook is correct before sharing or deployment.
Run witan xlsx render <file> -r "Sheet1!A1:Z50" to visually verify layout, then run witan xlsx calc <file> --verify and witan xlsx lint <file> to complete a non-mutating verification gate.

Render specific worksheet ranges to visually verify layout and formatting, then recalculate formulas to detect discrepancies and lint formulas to catch semantic bugs before sharing the workbook.
Excel workbook linting analyzes formulas for semantic issues and risky patterns that could lead to incorrect results. You need it before delivering updated workbooks to stakeholders to ensure formula integrity and prevent hidden bugs.
Run a verification calc on your xlsx file to recompute formulas and detect discrepancies between expected and computed values. This non-mutating check ensures calculation accuracy before deployment without altering the workbook.
Yes, Excel verification supports automation-ready JSON outputs for both calc and lint checks. The process enforces a verification gate with clear exit codes, enabling automated workflows to determine if a workbook passes validation.
Yes, Excel verification supports range-based checks, allowing you to target specific sheet ranges for rendering. The process is non-mutating, ensuring the original file remains unmodified during layout, calc, and lint checks.
Excel workbooks commonly drift after updates, retaining stale cached values and hidden formula bugs. Running a verification calc recomputes formulas to validate results and detect discrepancies between expected and computed values.
