## What it does

This skill supplies Claude Code with patterns for tabular data work. The agent learns to inspect multi-sheet workbooks and calculate group metrics. It also covers combining separate sheets by common keys.

Code patterns handle spreadsheet output with `openpyxl` and `pandas`. Claude Code can auto-fit column widths or highlight specific cell values. For visual charts, it relies on `matplotlib`.

All execution requires a local Python runtime. These dependencies are mandatory. When dealing with heavy datasets, the instructions suggest reading select columns with `usecols` or parsing rows in batches via `chunksize`.
