Fetches a remote `.xlsx` workbook and streams back a CSV file. The first sheet is exported by default; use `sheet_name` to target another tab.
This is the file-download counterpart to the JSON-returning [Excel to CSV](/convert/tools/excel-to-csv) endpoint.
Why Use This Tool
- Workbook archival — Normalize Excel archives to plain CSV for cold storage
- Automation hooks — Webhook-driven workbook-to-CSV conversion
- Browser downloads — One-click CSV export from an Excel source
- Pipeline ingestion — Pipe remote Excel files into line-oriented tooling
Frequently Asked Questions
Which sheet is used if none is specified?
The first worksheet in tab order is exported.
Are dates formatted?
Yes — Excel date cells are rendered as ISO-8601 strings (`YYYY-MM-DD` or `YYYY-MM-DDTHH:MM:SS`).
What about merged cells?
The merged value is written to the top-left cell; other cells are left blank.
