Can it handle existing Excel templates?

Absolutely. The skill is programmed to study and match existing formats, styles, and conventions, ensuring that modifications feel seamless and professional.

What libraries are used for data processing?

The skill uses pandas for high-performance data manipulation and openpyxl for granular spreadsheet formatting, cell styling, and formula management.

How does it ensure financial modeling accuracy?

It follows strict industry standards, including specific color coding (blue for inputs, black for formulas) and rigorous zero-error verification for all cell references.

Does this skill support complex Excel formulas?

Yes, it generates standard Excel formulas rather than hardcoding values, and includes a recalculation step to verify accuracy and resolve errors before the file is finalized.

Does it require external software for formula calculation?

It utilizes a recalc.py script that leverages LibreOffice to evaluate formulas, ensuring the final spreadsheet displays correct values immediately upon being opened.
