# Spreadsheet creation

> Generate CSV and Excel workbooks from Arka.

Create a workbook from a preset or schema:

```bash theme={null}
arka spreadsheet users --count 50 --output users.xlsx
arka spreadsheet sales --count 100 --output sales.xlsx
```

Arka uses the existing data generator, supports CSV/TSV/JSON/XLSX output,
and refuses unsafe overwrites according to the generator's output rules.
