Can I use this for professional financial modeling?

Absolutely. It follows strict industry standards, including blue-text for hardcoded inputs, black-text for formulas, and specific currency and percentage formatting.

What libraries are used for spreadsheet processing?

It primarily uses pandas for heavy data analysis and openpyxl for preserving complex formatting, formulas, and multi-sheet workbooks.

Can it detect formula errors like #REF! or #DIV/0!?

Yes, it runs a verification checklist after recalculation to identify and fix common Excel errors, ensuring publication-quality outputs.

Does this skill support automatic formula calculation?

Yes, it includes a mandatory recalculation step using a LibreOffice-powered script to ensure all formulas are evaluated and error-free before the file is finalized.

How does it handle existing Excel templates?

The skill is designed to match existing formats, styles, and conventions when modifying files, ensuring that template-specific patterns always override general guidelines.
