How to Use the cURL to Code Converter

To use the cURL to Code Converter, follow these steps:

1. Copy your cURL command from your browser DevTools, Postman, API docs, or terminal.

2. Paste the cURL command into the left panel of the converter. Multi-line commands with backslash continuation are supported.

3. Select your target language from the dropdown menu: Python, JavaScript fetch, Node.js axios, Go, or PHP.

4. Copy the generated code and paste it directly into your project. Start using it immediately!

  • Multi-line commands with backslash continuation are supported.
  • Choose from Python, JavaScript fetch, Node.js axios, Go, or PHP.
  • Error handling is included in the generated code.

When to Use the cURL to Code Converter

Use the cURL to Code Converter when you need to convert cURL commands to equivalent code in popular programming languages. This is particularly useful for developers working with HTTP APIs, automating tasks, or integrating with web services.

How It Works

The cURL to Code Converter works by parsing the cURL command and generating equivalent code in the selected programming language. It handles various cURL flags such as HTTP method, headers, request body, basic authentication, form data, cookies, and more. The converter ensures that the generated code is functional and adheres to best practices for the target language.

Tips, Edge Cases, and Limitations

1. Multi-line Commands: The converter supports multi-line commands with backslash continuation, making it easy to paste and format your cURL commands.

2. Language Selection: Choose from Python, JavaScript fetch, Node.js axios, Go, or PHP to get the code in your preferred language.

3. Error Handling: The converter ensures that the generated code includes proper error handling, which is crucial for reliable applications.

4. Security: The converter does not send your cURL command to a server. All processing happens on the client side, ensuring your data remains secure.

Frequently Asked Questions

The converter parses the most commonly used cURL flags: -X (method), -H (headers), -d/--data/--data-raw (request body), -u (basic auth), -F (form data), -b/--cookie (cookies), -L (follow redirects), -k/--insecure (skip SSL), and more.
The Python requests library is the de facto standard for HTTP in Python. It automatically handles JSON serialization, URL encoding, session management, and redirects. The library's API is clean and readable, making it the right choice for data science scripts, automation, CLI tools, and any Python application making HTTP calls.
fetch() is built into all modern browsers and Node.js 18+. It returns Promises and integrates naturally with async/await. Unlike axios, fetch does not automatically throw on HTTP error codes - you must check response.ok or response.status. Axios is a popular third-party HTTP client for Node.js and browsers, automatically parsing JSON response bodies and throwing errors on 4xx/5xx responses.
The converter automatically handles JSON serialization for request bodies when using languages like Python requests or JavaScript fetch. For Go, it uses the json.Marshal function to convert the JSON data into a string.
No, your cURL command is processed entirely on the client side. The converter does not send your cURL command to a server, ensuring your data remains secure.

Example walk-through

Worked example: step-by-step

Step 1. Paste a cURL command into the converter tool, ensuring it includes URL, headers, and request body.

Step 2. The tool parses the cURL command to identify HTTP method, URL parameters, headers, and payload data.

Step 3. step by step, the tool generates equivalent code using a target language (e.g., Python's requests library) with proper syntax and formatting.

Step 4. Review the generated code for accuracy, ensuring headers, authentication, and data payloads are correctly translated.

curl -X POST https://api.example.com/data \
-H "Authorization: Bearer YOUR_TOKEN" \
-H "Content-Type: application/json" \
-d '{"key":"value"}'
import requests

response = requests.post(
    'https://api.example.com/data',
    headers={
        'Authorization': 'Bearer YOUR_TOKEN',
        'Content-Type': 'application/json'
    },
    json={'key': 'value'}
)
