cURL to Code Converter

The Curl to Code tool converts any cURL command into equivalent code in Python (requests), JavaScript (fetch/axios), PHP (curl/Guzzle), Go, Ruby, Node.js, C#, and more. When working with API documentation, Postman exports, or debugging endpoints, you often end up with a cURL command that needs to be translated into your application\u2019s code. Manual translation is error-prone — headers get missed, body encoding differs, authentication format varies. This tool handles it all.

Paste any cURL command and pick your target language. The tool parses the command (handling -X, -H, -d, --data-binary, -u, --cookie, and many more flags), then generates idiomatic code for that language. Python uses requests library with correct header/data parameters. JavaScript uses either fetch API (modern browsers and Node 18+) or axios (popular HTTP client). Go uses net/http with correct request construction. Every language gets properly-escaped strings, error handling, and language conventions. All parsing and generation runs in your browser — API keys and endpoints stay private.

cURL parsing is the tricky part. cURL has many flags and variations:

Method: -X GET/POST/PUT/DELETE/PATCH. Default is GET (or POST if -d is present).

Headers: -H \"Name: Value\". Can have multiple -H flags.

Data:
- -d \"body\": URL-encoded form data (application/x-www-form-urlencoded)
- --data-raw: raw body, no processing
- --data-binary: raw body, preserves newlines
- --data-urlencode: URL-encode the given value
- -F: multipart form data (file uploads)

Authentication:
- -u user:pass: HTTP Basic Auth
- Bearer token: via -H \"Authorization: Bearer ...\"
- --digest: HTTP Digest Auth
- --anyauth: try multiple auth types

Cookies: --cookie or -b

SSL: -k or --insecure (skip cert verification), --cacert, --cert, --key

Redirects: -L or --location follows redirects

Output: -o file (write to file), -O (use remote name)

Generated code must handle these correctly. For example, a POST with -d \"key=value\":

Python (requests):
response = requests.post('https://api.example.com/endpoint',
headers={'Content-Type': 'application/x-www-form-urlencoded'},
data={'key': 'value'})

JavaScript (fetch):
fetch('https://api.example.com/endpoint', {
method: 'POST',
headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
body: 'key=value'
})

Header ordering, content-type inference from data, and auth conversion each have language-specific quirks. The tool knows these conventions.

Multi-line cURL with backslash continuation is handled: the parser joins lines and processes as one command.

Special characters: quotes, dollar signs, and backticks in cURL need escaping. The tool escapes correctly for each target language (Python f-strings vs JavaScript template literals vs PHP heredoc).

Multipart form (-F file=@/path/to/file): generated code uses the appropriate multipart library for each language (requests.post with files= in Python, FormData in JavaScript, etc.).

Cookies: some languages handle cookies differently (requests.session in Python, cookie jar in Go, Cookie header in JavaScript). The tool generates idiomatic code.

Compared to Postman\u2019s code generation (which is good but limited to a subset of languages), this tool supports more targets and handles more cURL features. Postman is great for API exploration; this tool is for quick translation.

Compared to Insomnia or other REST clients, this tool is a focused translator rather than full API client. Use REST clients for interactive testing; use this tool when you just need code.

Compared to writing code by hand from an API doc, this tool eliminates transcription errors and saves time on header mapping and body encoding.
