SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill solves the problem of producing correct, update-safe Excel spreadsheets by directly editing XLSX internals, ensuring calculated values remain formulas instead of stale hardcoded numbers.

Core Features & Use Cases

  • Spreadsheet creation and generation: Build new Excel workbooks from an XML template, writing every derived value as a live Excel formula.
  • Deterministic read + analysis: Inspect spreadsheet structure and analyze tabular data without modifying the source file.
  • Precise edit/fix/validate workflows: Perform minimal-invasiveness XML edits, repair broken formulas, and validate formulas via static and optional dynamic checks.

Quick Start

Use the minimax-xlsx skill to add formulas to your attached workbook.

Frequently Asked Questions about minimax-xlsx

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I edit Excel spreadsheets and keep formulas live instead of hardcoded values?▼

Direct XLSX XML unpacking and editing bypasses standard library round-trips, ensuring derived values remain update-safe formulas rather than stale hardcoded numbers.

Can I convert a CSV file to XLSX and insert spreadsheet formulas?▼

Yes, CSV to XLSX conversion supports inserting live Excel formulas. The workflow builds workbooks from XML templates, enforcing formula-first creation rules so calculated values are dynamic.

What is the best way to validate spreadsheet formulas before delivery?▼

Validating spreadsheet formulas involves running a static formula check script and optionally a dynamic LibreOffice tier 2 check to ensure formula delivery safety and repair broken formulas.

Does this approach support building financial modeling workbooks with pivot-like layouts?▼

Yes, financial modeling workbooks support pivot-like layouts and tabular modeling. The process handles workbook styling edits and generates structured spreadsheets using live Excel formulas.

Do I need openpyxl installed to read and analyze XLSX files?▼

No, you do not need openpyxl. The Skill routes read and analysis tasks directly to XML unpack and edit scripts, avoiding openpyxl round-trips to perform deterministic spreadsheet analysis.

Why does my spreadsheet formula break after editing the workbook?▼

Spreadsheet formulas break when standard library edits corrupt the internal XML structure. Minimal-invasiveness XML edits repair broken formulas while preserving the workbook's calculated values.
