Analyzing Spreadsheets

Built for when you need to generate, modify, or analyze Excel files programmatically without breaking formulas. Uses pandas for data operations and openpyxl for preserving formatting and Excel-specific features. The standout requirement is zero formula errors at delivery, enforced through mandatory recalculation with LibreOffice after any formula changes. Follows strict financial modeling conventions for color coding and structure. Good for automating spreadsheet workflows where you need the output to actually work when someone opens it in Excel, not just technically valid XLSX files full of #REF! errors. Explicitly scoped to spreadsheets only, so don't reach for this when you're dealing with Word docs or PDFs.
