About This Tool
Fetches a CSV file from a public URL and streams back an `.xlsx` workbook as a file download. This is the zero-JSON version of the [CSV to Excel](/convert/tools/csv-to-excel) endpoint, ideal for direct browser downloads and `curl -OJ` pipelines.
The remote CSV must be reachable over HTTPS without authentication. Headers and delimiter are auto-detected.
Why Use This Tool
- Browser downloads — Offer a one-click "Download as Excel" link from a CSV source
- CI exports — Convert CSV artifacts to Excel inside a build pipeline
- Shell scripts — Pipe `curl -OJ` directly into archival workflows
- No-JS integrations — Use in form submissions and HTML `<a>` tags
Frequently Asked Questions
Is the URL fetched server-side?
Yes. The service fetches the URL over the public internet. Private or auth-protected URLs are not supported.
What size limits apply?
Remote inputs are capped at the server-configured maximum (typically a few MB). For larger files, use the async jobs API.
What encodings are supported?
UTF-8 is the default. UTF-16 and Windows-1252 are auto-detected via BOM or heuristics.
