cURL to Code Converter

How to Use the cURL to Code Converter:

1. Load an Example (Optional): Click one of the example buttons at the top — GET + Auth, POST JSON, PUT Update, or DELETE — to pre-fill the input with a realistic cURL command. This is useful for getting familiar with the tool or testing edge cases before pasting your own command.

2. Paste Your cURL Command: Paste your cURL command into the input textarea. You can paste single-line or multi-line commands. Multi-line commands using backslash continuation () are automatically normalised. Copy the command directly from your terminal, API documentation, Postman, Insomnia, or a browser DevTools network request.

3. Select the Target Language: Click the language tab at the top of the output panel to choose your target: JS Fetch, Axios, Python, or PHP. You can switch between tabs at any time after conversion — the code is regenerated instantly without needing to click Convert again.

4. Click Convert: Click the Convert button. The tool parses your cURL command and generates equivalent code in the selected language. A parsed summary below the code block shows the detected method, URL, headers, and body type so you can verify the parse was correct.

5. Read the Generated Code: The code block shows production-ready code with proper indentation. For JSON bodies, the tool detects the content type automatically and generates idiomatic code: body: JSON.stringify({...}) for Fetch, data: {...} for Axios, json={...} for Python requests, and CURLOPT_POSTFIELDS for PHP.

6. Copy the Code: Click the Copy button in the top-right of the code panel to copy the generated snippet to your clipboard. Paste it directly into your project and run it without modification.

7. Verify the Parsed Summary: Check the Parsed Summary table below the code to confirm the method, URL, headers, and body were detected correctly. If the method shows GET when you expected POST, check that your cURL command includes -X POST or a -d flag.

8. Handle Authentication: The tool preserves Authorization headers exactly as written in your cURL command. Bearer tokens, API keys, and Basic auth (-u user:pass) are all carried through. For Basic auth provided with -u, the generated code includes the Authorization: Basic header with the base64-encoded credentials.

9. Test the Output: Paste the generated code into your project or a sandbox (StackBlitz, JSFiddle, Replit). For Python, run in a virtual environment with requests installed. For PHP, run with the cURL extension enabled. The generated code is minimal and has no extra dependencies beyond the specified library.

10. Reset for a New Command: Click Reset to clear the input and output and start fresh with a new cURL command.

Common Use Cases:

• API integration: Convert cURL examples from API documentation (Stripe, GitHub, Twilio, Shopify) into the language your project uses without rewriting the request manually.
• Debugging: Copy a failing request from browser DevTools as cURL and convert it to Python or Node.js to test it in isolation outside the browser.
• Code review: Quickly translate a cURL command shared by a teammate into the format used in your codebase.
• Learning: See how the same HTTP request looks across different languages and libraries side by side.
• Onboarding: Share code snippets with new team members in the language they know best.
• SDK migration: Convert legacy cURL-based scripts to modern Fetch or Axios calls when migrating to a JavaScript framework.
