All conversions are client-side. No network requests are made.
Copied a cURL command from Chrome DevTools, Postman, or API documentation? Paste it here and get clean, production-ready code in JavaScript (Fetch API), Python (Requests), or Go — with headers, body, and authentication properly formatted.

What is the Curl Converter?
The cURL to Code Converter parses standard cURL commands and generates equivalent, production-ready code snippets in popular programming languages. cURL is the universal HTTP client — browsers export network requests as cURL commands, API documentation often provides cURL examples, and developers use it for quick testing. This tool bridges the gap between command-line testing and production code by translating cURL's flag-based syntax into idiomatic code.
Real-World Use Cases
- Browser debugging — copy a cURL command from Chrome DevTools (right-click request → Copy as cURL) and convert it to Fetch API code for reproducing the request programmatically.
- API integration — convert cURL examples from API documentation (Stripe, Twilio, AWS) into production code in your application's language.
- Testing to production — translate ad-hoc cURL tests into proper HTTP client code with error handling and type safety.
- Cross-language migration — convert cURL commands to code in a new language when migrating services.
How to Use
- 1Paste your cURL command into the input editor.
- 2Select your target language (JavaScript, Python, Go).
- 3Review the generated code in the output panel.
- 4Copy the generated code snippet for your project.
Technical Deep Dive
cURL commands encode HTTP request details using command-line flags: -X for the method, -H for headers, -d for request body, --data-urlencode for form data, -u for basic authentication, and many more. Parsing these flags requires understanding cURL's complex argument syntax, including quoted strings, escaped characters, multiline commands (backslash continuation), and mutually exclusive options. The converter tokenizes the cURL command into its component parts, extracts the URL, HTTP method, headers, body, and authentication credentials, then generates idiomatic code for each target language. The JavaScript output uses the Fetch API (the modern standard for HTTP requests in browsers and Node.js). The Python output uses the popular Requests library with proper session handling. The Go output uses the net/http standard library. Each output includes proper error handling, content-type headers, and authentication setup.
Pro Tips & Best Practices
- When copying cURL from Chrome DevTools, choose 'Copy as cURL (bash)' for the cleanest output. The 'Copy as cURL (cmd)' variant uses Windows-specific quoting that may not parse correctly.
- If the conversion seems incorrect, check for multiline cURL commands — some terminals wrap long commands with backslashes (\) that may not copy correctly.
- The generated code includes all headers from the cURL command. In production, you may want to remove browser-specific headers like User-Agent, Accept-Encoding, and Cookie.
- For authenticated requests, the generated code uses the same authentication method as the cURL command. Always store credentials in environment variables, not hardcoded in source code.
