Can it modify existing Excel files without breaking them?

Absolutely. It is designed to study existing templates and match their formatting, styles, and conventions exactly when performing updates.

How are formula errors prevented?

The skill uses a mandatory recalculation script that scans for #REF!, #DIV/0!, and other errors, providing a detailed summary to fix issues before delivery.

Does this skill support complex Excel formulas?

Yes, it specifically prioritizes dynamic Excel formulas over hardcoded Python values to ensure workbooks remain interactive and updateable by users.

Is this suitable for investment banking or finance tasks?

Yes, it follows industry-standard conventions such as blue text for inputs, black for formulas, and specialized formatting for multiples and currency.

What software is required for the recalculation feature?

The skill assumes LibreOffice is installed to power the recalc.py script, which handles headless formula evaluation and error checking.
