How to convert a cURL command into application code
Turn a copied cURL request into Fetch, Axios, Python, Go or PHP code. Inspect the request and download snippets without sending the request or signing up.
- Paste one cURL command, import a small command file, or load a sample. Use Copy as cURL (bash) from browser developer tools.
- Choose Convert cURL, then inspect the method, URL, headers, authentication, query parameters and request body.
- Select a language and JavaScript runtime. Adjust response handling, timeouts, redirects or credential redaction, and read conversion notes.
- Copy the code, download a script or download the code bundle. Review credentials and run it in your own development environment.
When converting cURL to code is useful
API documentation often shows examples as cURL commands, and browser developer tools let you copy any network request in the same form. Turning that command into working code by hand is slow and easy to get wrong, especially with quoting, form data and authentication.
Developers use this converter to move a tested request into a Node.js script, a Python job, a Go service or a PHP page. It also helps when reproducing a bug report, because the request can be inspected field by field before you write any code around it.
The converter never runs the request. It only reads the text, so you can safely explore commands that point at production endpoints while deciding how to structure your code.
Worked example: a GET request with a bearer token
Paste this command: curl 'https://api.example.com/orders?status=open' -H 'Accept: application/json' -H 'Authorization: Bearer abc123' --max-time 20. After Convert cURL, the inspector shows the method GET, the URL with its status query parameter, two headers and a 20-second timeout.
Choose Python Requests and the script calls requests.request with method GET, the URL, both headers, allow_redirects set to False, verify set to True and timeout=(20, 20). It then raises an error for any status outside 200 to 299 and prints the response text. A note explains that Python Requests applies connect and read timeouts rather than one strict total deadline.
Turn on credential redaction and the header becomes Bearer REPLACE_WITH_TOKEN, so the snippet is safer to paste into a ticket or a shared repository.
How the parser reads a command
The parser understands common short and long flags such as -X, -H, -d, -F, -u, -G and -L, plus --json, --data-raw, --data-binary, --data-urlencode and --max-time. -G moves data into the query string, -u becomes basic authentication and -L turns on redirect following.
Output options include response handling as text, JSON or binary bytes, two-space, four-space or tab indentation, status checking and comments. For browser Fetch you can also choose whether cookies are omitted, sent to the same origin or included.
After parsing, everything is editable. You can change the method and URL, add or remove query parameters and headers, switch authentication between none, basic and bearer, and change the body format between raw or JSON text, URL-encoded form text, multipart fields and files, or a binary file path. Edits update the snippets but do not rewrite the original command.
Common mistakes to avoid
Do not choose browser output for a request that sets Cookie headers or reads local files. Browsers block some headers and apply CORS, so use Node.js, Python, Go or PHP instead.
Do not paste several commands at once; convert one request at a time. If you edit the cURL text after converting, select Convert cURL again, because the snippets stay blank until the command is parsed again. Finally, review every generated script before running it, since it will send real requests with any credentials it contains.
Useful tips and limitations
- File upload paths are references only; the generated program reads them when you run it.
- Browser snippets remain subject to CORS and browser restrictions. Use a server runtime for requests needing arbitrary Cookie headers or local file paths.
- Use the sample menu to see how JSON bodies, form uploads and binary file bodies are translated before pasting your own command.
- Read the conversion notes under the code, because they explain behavior that differs between cURL and the chosen library.
Common questions
Does converting cURL send my API request?
No. Parsing, editing and code generation happen locally. The tool does not execute the command, contact the API or store a request history.
Which output languages does the cURL converter support?
JavaScript Fetch, JavaScript Axios, Python Requests, Go net/http and PHP cURL. You can choose browser or Node.js output for JavaScript.
Can I convert JSON, form data and file uploads?
Yes. Common JSON, raw text, URL-encoded forms, multipart text and file fields, and binary file-body references are supported. Unsupported flags produce an error instead of being silently discarded.
Why can a cURL request fail when converted to browser Fetch?
Browsers enforce CORS, restrict headers and prohibit GET or HEAD request bodies. Select a server runtime or an appropriate output language when browser restrictions do not fit your request.
Will credential redaction remove every secret?
No. It replaces recognized authorization, cookie, token, password and key fields with placeholders. Review custom field names, raw text and file paths before sharing generated code.
What happens to display flags like -s or -v?
They are accepted but not translated, and a note explains that response and error handling are controlled by the converter options instead.
Does -G change the generated request?
Yes. With -G, data values are added to the URL query string and the request is sent as GET instead of carrying a body.
Can I change the indentation of the code?
Yes. Choose two spaces, four spaces or tabs, although Python output keeps four-space indentation because indentation is part of its syntax.
