# Column Charts Showcase

This demo consists of three files that work together:

- **charts-column.py** — Python script that calls `officecli` commands to generate the workbook. Each chart command is shown as a copyable shell command in the comments.
- **charts-column.xlsx** — The generated workbook with 8 sheets (1 data + 7 chart sheets, 28 charts total).
- **charts-column.md** — This file. Maps each sheet to the features it demonstrates.

## Regenerate

```bash
cd examples/excel
python3 charts-column.py
# → charts-column.xlsx
```
