xlsx

Create and modify .xlsx workbooks with the openpyxl Python library. Reading an existing spreadsheet to plain text is best done with the built-in os.fs.read_document tool (no install). Use the scripts below to write: new workbooks, cell values, formulas, and basic formatting.

The pattern is python3 -c "<inline script>" (or python3 script.py for longer logic). Keep scripts short and idempotent; always write to a fresh output path.

Setup health check (run first, every session)

Verify with one solo step:

[{ "tool": "os.shell.run", "args": { "cmd": "python3", "args": ["-c", "import openpyxl; print(openpyxl.__version__)"] } }]
