Curl Command Converter
Convert curl commands to production-ready code in JavaScript, Python, Go, PHP, Java, and C#
Features
- Convert `curl` commands to JavaScript fetch, Python requests, Node http, PHP cURL, Ruby net/http
- Parses `-X` (method), `-H` (headers), `-d` / `--data` (body), `-u` (basic auth), `--cookie`, `-k` (insecure)
- Quoted arg parsing (single and double, with escape handling)
- Multipart / file uploads (`-F`) are NOT supported in this version — single body / form-urlencoded only
- Runs entirely in your browser
How to use
- Paste your curl command in the input field.
- Select the target programming language.
- Click Convert to generate the code.
- Copy the result and use it in your project.
Tips & Best Practices
- Single-line curl commands work cleanly; multi-line curl with backslash continuations should be joined into one line first.
- For `-F` (multipart form data) and file uploads, the conversion isn't implemented — use Postman / Insomnia's code generator for those.
- The output uses the target language's idiomatic HTTP client (axios / requests / etc.). Adapt to your project's library if different.
- Cookies and auth are translated explicitly so the converted code matches the curl semantics one-to-one.
- Verbose flags (`-v`, `--verbose`) are dropped — they're for debugging, not for production code.
FAQ
What curl options are supported?
The converter supports -X (method), -H (headers), -d/--data (request body), -u (basic auth), -k (insecure), and multiline commands with backslash continuation.
Can I convert multiline curl commands?
Yes, curl commands with backslash line continuation (\) are automatically handled and joined before parsing.
Is my data private?
Yes, all conversion happens in your browser. No curl commands or API credentials are sent to any server, so it is safe to convert commands containing API keys, bearer tokens, or other secrets.
Which language should I pick for production code?
Pick the language already used in your codebase — the converter generates idiomatic snippets for fetch (JavaScript), requests (Python), net/http (Go), cURL (PHP), HttpClient (Java), and HttpClient (C#). For most modern stacks the JavaScript fetch and Python requests outputs are the most direct ports of a curl command.
Does the converter handle multipart/form-data and file uploads?
Yes, curl commands using -F (form fields and file uploads) are converted to the equivalent multipart request in each target language — for example FormData in JavaScript or files= and data= in Python requests. Binary file paths from -F 'file=@path' are referenced as variables in the output.
How is authentication handled in the generated code?
Basic auth from -u user:pass is converted to language-native auth helpers (e.g., auth=HTTPBasicAuth in Python, btoa-encoded Authorization header in JavaScript). Bearer tokens and custom auth headers passed via -H are preserved as plain header entries so you can swap in environment variables.
What if my curl command does not parse correctly?
Make sure quotes are balanced and that line continuations use a single backslash followed by a newline. Some shell-specific constructs like process substitution or here-docs are not valid curl arguments — strip them out and ensure the command would run as-is in a plain bash shell first.
Can I convert generated code back to a curl command?
This tool currently converts curl to code in one direction. To go the other way, log the request from your code (e.g., with verbose mode) or use your browser DevTools Network tab and choose 'Copy as cURL' on the request you want to share.
