CURL to Fetch Converter Online

Convert curl to fetch, axios, and back

Documentation and browser devtools often ship requests as curl one-liners, while frontend code uses fetch or axios. This converter bridges those formats instantly—headers, methods, and bodies preserved—so you can paste from Network tabs into application code without manual rewrites.

How teams use it

Paste a curl from Postman or Swagger into fetch for a React prototype. Convert axios integration tests to curl for reproducing bugs in terminal. Pair with our regex tester when parsing log lines and the URL encoder for query-string edge cases.

Best practices

Redact bearer tokens before sharing converted snippets. Re-run conversion after you edit headers manually—auto detection picks curl, fetch, or axios from the input shape.

Built for frontend and backend handoffs

curl → fetch and curl → axios via battle-tested parsing—headers and bodies stay intact.
Reverse conversions from fetch or axios back to curl for terminal reproduction.
Auto-detects input format so you spend less time picking dropdowns.
Download snippets as .js or .sh files for docs and runbooks.

Frequently asked questions

How to convert curl to fetch?

Paste your curl command, select JavaScript fetch as output, and click Convert. The result is a fetch(url, options) block you can paste into browser code.

Does it support headers?

Yes. Authorization, Content-Type, and custom headers are preserved in conversions.

Does it support POST requests?

Yes. Request bodies from --data, --data-raw, and JSON payloads carry over to fetch and axios output.

Can I convert fetch back to curl?

Yes. Paste a fetch() call, choose curl as output, and copy a curl command for terminal debugging.
