Curl to Code Converter
Paste a curl command, pick a target language. Generates fetch, requests, Cypress, or Playwright code.

Code will appear here…HOW TO USE
- 01Paste a curl command — multi-line continuations (lines ending in \) are supported.
- 02Pick a target language. Recognized flags: -X, -H, -d, --data*, -u, -b, -A, -e.
- 03JSON request bodies are detected automatically and emitted as native objects (e.g. JSON.stringify, json=, data:).
WHEN TO USE
Use this when you copy a curl command from browser DevTools, Postman, API documentation, or a bug report and need to turn it into test code. It handles the mechanical translation of flags (-X, -H, -d, -u, -b, -A) into the request method, headers, body, auth, and cookies of the target language. Use it as the first step when adding a new API endpoint to your test suite — paste the working curl, generate the scaffold, then add assertions.
WHAT BUGS THIS FINDS
Header casing inconsistency
A server rejects a request because Content-Type is sent as content-type in the generated code — inspect the converted output to confirm header names match the casing the API expects.
Body encoding mismatch
A -d flag with form data is converted as a JSON body (or vice versa) when Content-Type is ambiguous — verify the generated body encoding matches what the curl command actually sends.
Auth flag lost in translation
The -u user:password flag translates to Basic Auth in curl but may be omitted or incorrectly placed in the generated code — confirm the Authorization header is present and correctly base64-encoded.
Multi-line curl parsed incorrectly
A curl command copied from docs with line continuations (\) may have extra whitespace added by the terminal — the converter handles continuations explicitly, surfacing parse errors before the code is executed.
QA USE CASES
API test scaffold from DevTools
Copy a request from browser DevTools as curl, convert to your test language, and use the output as the starting point for a new test case — all headers, auth, and body included.
Bug reproduction test from curl
Convert a curl command from a bug report into the same language as your test suite to create a reproducible failing test that validates the fix when it passes.
Auth endpoint coverage
Convert the curl examples from an API's authentication docs into test code for each auth method (Basic, Bearer, cookie) to build out auth coverage quickly without writing boilerplate.
