How does this skill handle Excel formulas?

It prioritizes dynamic Excel formulas over hardcoded Python values to ensure workbooks remain updateable, and uses a LibreOffice-based script to recalculate and verify results.

Does it support professional financial modeling standards?

Yes, it implements industry conventions such as blue text for hardcoded inputs, black for formulas, and specific formatting for multiples (0.0x) and negative numbers.

Can I use this to modify existing Excel templates?

Absolutely. The skill is designed to study and match existing formats and styles, ensuring that template conventions always override default guidelines during updates.

How are formula errors prevented?

The skill utilizes a 'recalc.py' script that scans all cells for errors like #REF!, #DIV/0!, and #VALUE!, providing a JSON summary of any issues that need fixing.

Which Python libraries are used for processing?

The skill primarily uses pandas for heavy data manipulation and analysis, and openpyxl for complex formatting, styles, and preserving workbook structure.
