Convert cURL Commands to Python, JavaScript, and More

Our cURL converter tool helps developers quickly convert cURL commands to Python requests, JavaScript fetch, and other programming languages. Perfect for API integration, testing, and code migration.

What is cURL?

cURL (Client URL) is a command-line tool for transferring data using various network protocols. It's widely used for testing APIs, making HTTP requests, and debugging network issues. However, when integrating APIs into applications, developers often need to convert these cURL commands to their programming language of choice.

Supported Conversions

• Python (requests): Convert to Python using the popular `requests` library
• JavaScript (fetch): Convert to modern JavaScript using the Fetch API
• JavaScript (axios): Convert to JavaScript using the Axios library
• Java (OkHttp): Convert to Java using the OkHttp library

Supported cURL Features

Our converter supports all major cURL options:

• HTTP Methods: GET, POST, PUT, DELETE, PATCH, HEAD, OPTIONS
• Headers: Custom headers including Content-Type, Authorization, etc.
• Request Body: JSON, form data, raw data
• Authentication: Basic auth, Bearer tokens, API keys
• Cookies: Cookie handling
• Redirects: Follow or manual redirect handling

How to Use

1. Copy your cURL command from your browser's developer tools, Postman, or any API testing tool
2. Paste it into the input field above
3. Click "Convert cURL" to generate code
4. Select the language tab (Python or JavaScript)
5. Copy the generated code and use it in your project

Common Use Cases

• API Integration: Convert API documentation examples to working code
• Testing: Convert Postman or Insomnia cURL exports to test scripts
• Code Migration: Convert cURL commands from documentation to your codebase
• Learning: Understand how cURL commands translate to code
• Quick Prototyping: Rapidly convert API calls to working code

Example cURL Commands

Simple GET Request

curl https://api.example.com/users

POST with JSON Data

curl -X POST https://api.example.com/users \
  -H 'Content-Type: application/json' \
  -d '{"name": "John", "email": "[email protected]"}'

With Authentication

curl -X GET https://api.example.com/profile \
  -H 'Authorization: Bearer your-token-here'

With Basic Auth

curl -X GET https://api.example.com/data \
  -u username:password

Python requests Library

The generated Python code uses the `requests` library, which is the most popular HTTP library for Python. To use it, install requests:

pip install requests

The generated code includes proper error handling, headers, and data formatting.

JavaScript Fetch API

The generated JavaScript code uses the modern Fetch API, which is built into modern browsers and Node.js (with node-fetch). The code includes proper promise handling and error management.

JavaScript Axios

The Axios version uses the popular Axios library, which provides a more feature-rich API than fetch. To use it, install axios:

npm install axios

or include it via CDN. Axios provides better error handling, request/response interceptors, and automatic JSON parsing.

Java OkHttp

The generated Java code uses OkHttp, a popular HTTP client library for Java and Android. To use it, add the dependency to your project:

// Maven
<dependency>
    <groupId>com.squareup.okhttp3</groupId>
    <artifactId>okhttp</artifactId>
    <version>4.12.0</version>
</dependency>

// Gradle
implementation 'com.squareup.okhttp3:okhttp:4.12.0'

The generated code includes proper exception handling and resource management.

Tips for Best Results

• Complete Commands: Include the full cURL command with all options
• Proper Formatting: Multi-line cURL commands with backslashes are supported
• Check Headers: Review generated headers to ensure they match your needs
• Test Generated Code: Always test the generated code in your environment
• Handle Errors: Add error handling to the generated code as needed

Limitations

• File uploads (@filename) are not fully supported - manual adjustment may be needed
• Complex authentication schemes may require manual configuration
• Custom SSL certificates and certificates are not converted
• Proxy settings are not included in the conversion

Privacy & Security

All conversion happens entirely in your browser. No cURL commands, URLs, headers, or data are sent to our servers. Your API keys, tokens, and sensitive information remain completely private and secure.

Why Use This Tool?

• Time-Saving: Convert cURL commands in seconds instead of manually writing code
• Accuracy: Avoid manual errors when converting complex commands
• Learning: Understand how HTTP requests translate between formats
• Standardization: Generate consistent, readable code
• Free: No account required, unlimited conversions
