Create and edit Excel spreadsheets (.xlsx): multiple sheets, live formulas, professional formatting, and data tables. Use whenever the user asks to build, populate, or modify a spreadsheet/workbook/Excel file.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Create & edit Excel spreadsheets with openpyxl
Build real `.xlsx` files with the open-source **openpyxl** library (available as
`python3 -c "import openpyxl"`). Work in visible steps and verify before you
report done.
## Workflow (one step at a time)
1. **Plan** the sheet(s), columns, and any formulas/totals.
2. **Write a short Python script** (a heredoc through the `bash` tool) that builds
the workbook with openpyxl and saves it to the requested path.
3. **Verify**: reopen with `load_workbook(path)` and `assert` the key cells and
formulas are present, then `print(path)`.
4. **Report** the saved path and a one-line summary.
## Quality conventions
- **Header row**: bold, light fill (`PatternFill('solid', fgColor='D9EAF7')`), thin borders.
- **Use formulas, never hardcoded totals**: e.g. `ws['B5'] = '=SUM(B2:B4)'`.
- **Number formats**: currency `'$#,##0;($#,##0);-'`, percent `'0.0%'`, multiples `'0.0x'`.
- **Financial color convention** (optional, for models): blue font (`Font(color='0000FF')`)
for hardcoded inputs, black for formulas, green for cross-sheet links.
- Size column widths to content; `ws.freeze_panes = 'A2'` to keep headers visible.

How to install
mdr add phuetz/code-buddy/xlsx@sha256:9c03f57e41efc6feThe line at the top of this page pins the label git:20260616.904f11f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
