How does it handle formula errors like #REF! or #DIV/0!?

The skill includes a mandatory verification step using a recalculation script that scans every cell for errors and provides a detailed report to fix them automatically.

Why is LibreOffice mentioned in the requirements?

LibreOffice is used as a headless engine to recalculate formula results within the .xlsx file, ensuring the file is fully updated when opened in Excel.

Can I use this for professional investment banking models?

Absolutely. It follows industry-standard conventions such as blue text for hardcoded inputs, black for formulas, and green for internal worksheet links.

Does this skill support complex Excel formulas?

Yes, it prioritizes dynamic Excel formulas over hardcoded Python values and uses a dedicated recalculation script to ensure all cell values are accurate.

What Python libraries are required for this skill?

It primarily utilizes pandas for data-heavy analysis and openpyxl for tasks requiring specific formatting, styles, and formula construction.
