Summary
This one enforces professional Excel standards for financial models: blue text for inputs, black for formulas, green for internal links, plus proper number formatting and zero tolerance for formula errors. It pushes you to use Excel formulas instead of hardcoding Python calculations, which keeps spreadsheets dynamic. The workflow is openpyxl for construction plus a LibreOffice recalc script that catches #REF! and #DIV/0! errors before delivery. Honestly most useful if you're building models that need to follow investment banking conventions or need to hand off working spreadsheets to non-technical users who'll actually modify assumptions.
