Curl to Code Converter
LiveConvert cURL commands to JavaScript, Python, PHP, Go, and more.
Understanding URL Encoding & Structure
cURL commands are the de facto standard for documenting and testing HTTP API requests — API documentation, Stack Overflow answers, developer tools, and API testing platforms all output cURL commands. However, production application code uses language-specific HTTP clients (fetch, axios, requests, HttpClient). Converting cURL commands to code in your target language eliminates the tedious manual translation of headers, authentication, request bodies, query parameters, and HTTP methods into language-specific API call syntax.
Use this free cURL converter to transform curl commands into code in your language of choice. Supports JavaScript fetch, Axios, Python requests, Go http, PHP cURL, Ruby, Java, and C#. Parses headers, POST data, cookies, authentication, and query parameters. Convert curl to code for any REST API integration workflow.
The Devkitr cURL to Code Converter translates cURL commands into production-ready code for JavaScript (fetch/axios), Python (requests), PHP (cURL/Guzzle), Go, Ruby, Java, and C#. Paste a cURL command to get the equivalent HTTP request code in your target language, complete with headers, authentication, and request body.
In a typical development workflow, Curl to Code Converter becomes valuable whenever you need to convert curl commands to javascript, python, php, go, and more. Whether you are working on a personal side project, maintaining production applications for a company, or collaborating with a distributed team across time zones, having a reliable browser-based conversion tool eliminates the need to install desktop software, write one-off scripts, or send data to third-party services that may log or retain your information. Since Curl to Code Converter processes everything locally on your device, your data stays private and your workflow stays uninterrupted — open a browser tab, paste your input, get your result.
Key Features
Multi-Language Output
Generates code for JavaScript (fetch, axios, node-fetch), Python (requests, urllib), PHP, Go, Ruby, Java (HttpClient/OkHttp), and C# (HttpClient).
Full cURL Flag Parsing
Handles -X (method), -H (headers), -d (data), -u (auth), --data-raw, --data-binary, -F (form data), -k (insecure), and other common flags.
Authentication Handling
Converts -u user:pass to Basic auth headers, and -H "Authorization: Bearer ..." to proper auth configuration in each language.
Request Body Formatting
Translates JSON bodies, form data, multipart uploads, and raw data to the appropriate language-specific request body format.
How to Use Curl to Code Converter
Paste cURL Command
Enter the cURL command from API documentation, browser DevTools "Copy as cURL", or any cURL source.
Select Target Language
Choose your programming language and preferred HTTP library (fetch vs axios, requests vs urllib).
Review Generated Code
Check the code for correct URL, method, headers, authentication, and request body translation.
Copy and Integrate
Copy the generated code into your application, adjusting variable names and error handling as needed.
Use Cases
API Integration Development
Convert API documentation cURL examples to your application's language for rapid integration implementation.
Browser Request Reproduction
Copy requests as cURL from browser DevTools and convert to application code for reproducing and debugging API interactions.
Postman/Insomnia Export
Export requests as cURL from API testing tools and convert to production code in your application's language.
Multi-Language SDK Examples
Generate API call examples in multiple languages from a single cURL command for API documentation that serves polyglot teams.
Pro Tips
Copy cURL commands from browser DevTools (Network tab → right-click → Copy as cURL) to capture exact headers, cookies, and request bodies.
Remove sensitive headers (cookies, auth tokens) from the cURL command before converting — generated code should not contain hardcoded credentials.
For multiline cURL commands, ensure line continuation characters (\) are preserved when pasting.
After conversion, add proper error handling — generated code typically shows the happy path without try/catch or status code checking.
Common Pitfalls
Including hardcoded authentication tokens in generated code
Fix: Replace literal auth tokens with environment variables or secure credential storage. Never commit API keys in source code.
Not adding error handling to the generated code
Fix: Generated code shows the request but not error handling. Add try/catch, status code checks, and timeout handling for production use.
Assuming the generated code handles all edge cases
Fix: Generated code translates the cURL command literally. Add retry logic, rate limiting, pagination, and connection pooling for production applications.
