Curl to Fetch / Axios Converter

API documentations and developer tools like Postman export request examples as cURL terminal commands. Manually rewriting cURL flags (-X, -H, -d, -u) into your backend or frontend application language is tedious and prone to syntax errors. This converter tokenizes cURL commands and outputs clean, idiomatic code across modern programming languages instantly.

// Input cURL Command:
curl -X POST https://api.example.com/v1/auth \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer secret_token" \
  -d '{"username": "alex", "role": "admin"}'

// Generated JavaScript Fetch snippet:
fetch("https://api.example.com/v1/auth", {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
    "Authorization": "Bearer secret_token"
  },
  body: JSON.stringify({
    username: "alex",
    role: "admin"
  })
});

Developers work across diverse tech stacks. You can instantly toggle between native JavaScript fetch(), modern Axios config objects, Python requests, Go native net/http calls, Node.js https, and PHP curl_exec. If your converted payload requires TypeScript type declarations, use our JSON to TypeScript generator.

When cURL commands pass JSON strings via -d or --data-binary, the converter checks and formats the JSON payload. If the cURL payload has syntax issues, use our JSON Formatter to auto-fix and validate the data structure before embedding it into your codebase.

Terminal cURL commands frequently contain sensitive production API keys, Bearer tokens, or private endpoint credentials. This converter executes entirely inside your browser's local JavaScript environment. Zero request logs or header data are sent to external servers, protecting your secrets.
