cURL to Code Converter

Q: Is my curl command or any credentials in it sent to a server?

No. Parsing and code generation both run entirely client-side in your browser. The command, including any tokens, passwords, or Authorization headers, never leaves your machine and the request itself is never executed.

Q: How should I quote a JSON body in the curl command?

Wrap it in single quotes, e.g. -d '{"name": "Ada"}'. Single quotes avoid any shell interpretation of the double quotes inside the JSON. If you must use double quotes around the whole body, escape the inner quotes: -d "{\"name\": \"Ada\"}".

Q: What happens to flags like -L, -k, or --compressed?

They're recognized (so the command doesn't get rejected) but aren't represented in the generated code, since most HTTP client libraries handle redirects and compression by default and skipping TLS verification isn't something to encode by default. A note is shown whenever one of these flags is used.

Paste a curl command below. It's parsed entirely in your browser — the request is never sent anywhere, and credentials in the command are never transmitted. Shell features this tool can't safely interpret (variable expansion, command substitution, pipes, unrecognized flags) are rejected explicitly rather than guessed at.

cURL conversion examples

A useful conversion preserves the method, headers, authentication, query parameters, and exact request body.

JSON POST

curl -X POST -H 'Content-Type: application/json' -d '{"name":"Ada"}' https://api.example.invalid/users

Generated clients should send the same JSON bytes with the same content type.

Query-string GET

curl 'https://api.example.invalid/posts?userId=1'

The URL carries filtering state; no request body is needed.

Common mistakes

Copying real Authorization headers into shared examples.
Assuming shell variables can be converted without their runtime values.
Dropping flags without checking the converter's notes.

FAQ

Is my curl command or any credentials in it sent to a server?

Why do some curl commands get rejected instead of converted?

This tool intentionally supports a well-defined subset of curl: common flags like -X, -H, -d/--data*, -u, -A, -b, and a plain URL. Shell features it cannot safely resolve locally — environment variable expansion ($VAR), command substitution ($(...) or backticks), pipes, redirections, and multi-command chaining (;, &&) — are rejected with a clear error instead of being silently (and incorrectly) parsed.
