cURL to Code: Convert Terminal Commands to Python, JavaScript, Go, and More

Stack Overflow answers and API docs often provide examples as cURL commands. Translating those into your application's language by hand is tedious and error-prone. A cURL-to-code converter does it instantly, producing idiomatic code with correct headers, auth, and body formatting.

What Is cURL to Code?

This tool parses a cURL command and generates equivalent HTTP request code in languages like Python (requests), JavaScript (fetch/axios), Go (net/http), PHP (curl), Ruby (net/http), and more. It handles headers, cookies, authentication, multipart uploads, and query parameters.

How to Use cURL to Code on DevToolHub

1. Open the cURL to Code tool on DevToolHub — no signup required.
2. Paste your cURL command into the input field — including all flags.
3. Select your target language and library (e.g., Python requests, JS fetch).
4. Review the generated code in the output panel.
5. Copy the code and integrate it into your project.
6. Adjust any environment-specific values like API keys.

Converting a cURL POST to Python

Starting with a typical cURL command:

curl -X POST https://api.example.com/users \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer tok_live_abc" \
  -d '{"name":"Alice","role":"admin"}'

Converts to clean Python:

Generated Python Code

The output uses the requests library with proper structure:

import requests

response = requests.post(
    'https://api.example.com/users',
    headers={
        'Content-Type': 'application/json',
        'Authorization': 'Bearer tok_live_abc',
    },
    json={'name': 'Alice', 'role': 'admin'},
)

print(response.status_code)
print(response.json())

Notice how -d with JSON content type automatically becomes the json= parameter — not raw string data.

Converting to JavaScript Fetch

The same cURL becomes modern JavaScript:

fetch('https://api.example.com/users', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'Authorization': 'Bearer tok_live_abc',
  },
  body: JSON.stringify({
    name: 'Alice',
    role: 'admin',
  }),
})
  .then(res => res.json())
  .then(data => console.log(data));

Each language output follows its community's idioms and best practices.

Pro Tips

• Include all flags — don't strip -k or --compressed as they affect the generated code.
• Replace secrets after copying — never commit hardcoded tokens from converted commands.
• Try multiple libraries — for JavaScript, compare fetch vs axios output and pick what fits your codebase.
• Handle multipart uploads — the converter correctly translates -F flags into FormData.

When You Need This

• Integrating a third-party API from its cURL-only documentation
• Porting a working cURL prototype into production application code
• Teaching junior developers how HTTP libraries map to raw HTTP concepts
• Migrating API calls between languages during a rewrite
