Can it convert curl to Python requests with authentication?

Yes. The converter handles both Basic Auth (-u user:pass) and Bearer token auth (-H 'Authorization: Bearer token'). For Basic Auth, it generates requests.get(url, auth=('user','pass')). For Bearer tokens, it adds the Authorization header to the headers dict.

Does it support multipart/form-data file uploads?

Not yet. The current parser handles -d (--data) and --data-raw for JSON and form-encoded bodies. --form (-F) for multipart file uploads is not supported in this version. Use the generated code as a starting point and add the files parameter manually.

How do I convert a curl command with JSON body?

Simply paste your curl command with -d '{"key":"value"}' into the input. The parser auto-detects JSON bodies and generates proper code: requests.post(url, json=data) in Python, JSON.stringify() in Node.js, and BodyPublishers.ofString() in Java.

What curl flags does the converter support?

The converter supports: -X (method), -H/--header (headers), -d/--data/--data-raw (request body), -u (Basic Auth), --compressed (adds Accept-Encoding comment), -k/--insecure (adds verify=False comment), -L/--location (adds follow redirects comment). Multi-line commands with backslash continuation are fully supported.

Can I convert curl to Node.js fetch with async/await?

Yes. The Node.js output uses modern async/await syntax with the built-in fetch API (Node 18+). The generated code wraps the fetch call in an async IIFE so you can run it directly. It includes proper error handling comments for production use.

Why does my curl command fail to parse?

Common issues include: unescaped nested quotes (use alternating single/double quotes), missing URL (every curl command needs a URL), --data-binary or --form flags (not yet supported), and Windows-style line endings. Try simplifying your command or removing unsupported flags, then add the missing parts manually to the generated code.

Is my API data safe when using this converter?

Yes. All parsing and code generation happens entirely in your browser using JavaScript. No data is ever sent to any server. Your curl commands, API keys, tokens, and credentials never leave your device. We recommend redacting real production credentials before pasting as your screen may be visible to others.

What Is cURL to Code Converter?

cURL to Code Converter is a free, browser-based developer utility that converts cURL commands into ready-to-use code in Python (requests), Node.js (fetch), and Java (HttpClient). It solves the problem of manually translating curl commands from API documentation into production code. No downloads, no sign-ups — everything runs locally in your browser.

Key Features

3 Target Languages: Generate Python (requests library), Node.js (fetch with async/await), and Java (HttpClient) code with a single click.
Full Header Parsing: All -H and --header flags are extracted including Authorization, Content-Type, custom headers — everything transfers to generated code.
Auth Detection: Automatically detects Basic Auth (-u user:pass) and Bearer tokens from Authorization headers, generating proper auth code in each language.
JSON Body Smart Detection: When the -d/--data body looks like JSON, generates json= parameter in Python, JSON.stringify() in Node.js, and proper string body in Java.
Method Recognition: Parses -X GET/POST/PUT/DELETE/PATCH, auto-infers POST when --data is present without explicit -X.
Multi-line Support: Handles backslash (\) line continuations exactly like a real shell, so you can paste formatted curl commands directly.

📋 When to Use cURL to Code Converter

Use this tool when you're reading API documentation (Stripe, GitHub, AWS, Twilio, OpenAI) and find a curl example you need to integrate into your application. Instead of manually rewriting headers into dicts, configuring HTTP clients, and handling auth, paste the curl command and get production-ready code in seconds. It's also perfect for sharing API call examples with teammates in their preferred language, or for quickly testing an API endpoint by generating a Python/Node/Java script.

⚙️ How cURL to Code Converter Works

The converter uses a JavaScript-based parser that tokenizes the curl command string. It identifies the URL, HTTP method flags (-X), header flags (-H/--header), data flags (-d/--data/--data-raw), auth flags (-u), and common behavioral flags (--compressed, -k, -L). Multi-line commands are normalized by removing backslash continuations. The parsed structure is then rendered through language-specific templates that produce idiomatic code — requests.post() in Python, fetch() in Node.js, and HttpClient.send() in Java. All parsing happens client-side in your browser; nothing is ever sent to a server.

How to Use cURL to Code Converter

Paste your curl command into the left panel. You can copy directly from API docs or your terminal.
Select your target language by clicking the Python, Node.js, or Java tab above the output panel.
Review the generated code — it appears instantly. Add error handling and timeouts before using in production.
Click the Copy button to copy the code to your clipboard, then paste it into your project.

🔐 When NOT to Use & Security Notes

Never paste curl commands with real production credentials — the parsing happens client-side but your screen may be visible. Redact tokens/passwords before pasting.
The parser handles standard curl syntax but may not parse edge cases like --data-binary, --form, or complex nested quoting. Always review generated code before running.
Generated code is a starting point — add error handling, timeouts, and retry logic for production use. The output omits try/catch blocks for brevity.
Generated Java code uses HttpClient from java.net.http (Java 11+). For older Java versions, use HttpURLConnection or a third-party library.
All processing is local — your curl commands, API keys, tokens, and credentials never leave your device. No server-side processing, no logs, no tracking of your input.

Frequently Asked Questions

1. Can it convert curl to Python requests with authentication?: Yes. The converter handles both Basic Auth (-u user:pass) and Bearer token auth (-H 'Authorization: Bearer ...'). For Basic Auth, it generates requests.get(url, auth=('user','pass')). For Bearer tokens, it adds the Authorization header to the headers dict. API key headers and custom auth schemes are also supported.
2. Does it support multipart/form-data file uploads?: Not yet. The current parser handles -d (--data) and --data-raw for JSON and form-encoded request bodies. The --form / -F flag for multipart file uploads is not supported in this version. Use the generated code as a starting point and add the files parameter (Python) or FormData (Node.js) manually.
3. How do I convert a curl command with JSON body?: Simply paste your curl command with -d '{"key":"value"}' into the input. The parser auto-detects JSON bodies and generates proper code: requests.post(url, json=data) in Python, JSON.stringify() in Node.js, and BodyPublishers.ofString() in Java. Single and double quotes are handled automatically.
4. What curl flags does the converter support?: The converter supports: -X (HTTP method), -H / --header (request headers), -d / --data / --data-raw (request body), -u (Basic Authentication), --compressed (adds Accept-Encoding comment), -k / --insecure (adds SSL verification disabled comment), and -L / --location (adds follow redirects comment). Multi-line commands with backslash continuation are fully supported.
5. Can I convert curl to Node.js fetch with async/await?: Yes. The Node.js output uses modern async/await syntax with the built-in fetch API (available in Node.js 18+). The generated code wraps the fetch call in an async IIFE so you can run it directly. It includes comments for adding proper error handling for production use.
6. Why does my curl command fail to parse?: Common issues include: unescaped nested quotes (use alternating single/double quotes or escape with backslash), missing URL (every curl command needs a target URL), --data-binary or --form flags (not yet supported), and Windows-style line endings (CRLF instead of LF). Try simplifying your command or removing unsupported flags, then add the missing parts manually to the generated code. The error message will indicate what went wrong.
7. Is my API data safe when using this converter?: Yes, completely safe. All parsing and code generation happens entirely in your browser using JavaScript — no data is ever sent to any server. Your curl commands, API keys, tokens, and credentials never leave your device. We do recommend redacting real production credentials before pasting into any browser-based tool, as your screen may be visible to others in shared workspaces.
