Why does it use a recalculation script?

Since libraries like openpyxl save formulas as strings, the included recalc.py script uses LibreOffice to evaluate those formulas so the file is ready for use immediately upon opening.

How does this skill handle Excel formula errors?

The skill includes a mandatory verification step using a recalculation script that scans for errors like #REF!, #DIV/0!, and #VALUE!, ensuring models are delivered with zero formula errors.

Does it follow standard financial modeling practices?

Yes, it defaults to industry standards: blue text for hardcoded inputs, black for formulas, and green for internal links, ensuring professional compatibility.

Can it modify my existing corporate templates?

The skill is specifically programmed to study and match existing formats, styles, and conventions, ensuring any modifications blend perfectly with your established patterns.

Does it support large dataset analysis?

Yes, it utilizes the pandas library for efficient data analysis, statistics, and bulk operations before applying formatting with openpyxl.
