What it does
Create, edit, analyze, or convert Excel spreadsheets (.xlsx, .xlsm, .xltx) where the workbook file is the primary deliverable. Use for formulas, formatting, financial models, multi-sheet workbooks, and tabular cleanup exported to Excel. Also applies to .csv/.tsv when the user wants spreadsheet output. Do NOT use for Word documents, HTML reports, standalone Python scripts, database pipelines, or Google Sheets API work.
XLSX creation, editing, and analysis
| Task | Approach |
|---|---|
| Create or edit with formulas/formatting | openpyxl, see gotchas below |
| Bulk data in or out | pandas (read_excel, to_excel) |
| Quick look at a sheet | markitdown file.xlsx, ## SheetName per sheet; reads .xlsm too. No cell coordinates, so don't plan edits from it |
| Read a model (formulas and values) | two load_workbook passes, see gotchas |
openpyxl,pandas, andmarkitdownare preinstalled, do not runuv pip installfirst; write the script and import directly. Only if an import fails (or themarkitdowncommand is missing):uv pip installthe missing package.
