Why Convert cURL?

API documentation almost always provides cURL examples because cURL is universal and language-agnostic. But when you're building a JavaScript or Python application, you need to translate those examples into your language's HTTP client. Manually translating cURL to Fetch or Axios is tedious and error-prone — especially for complex requests with multiple headers and JSON bodies. This tool does the translation instantly, saving time and preventing mistakes.

Benefits

  • Save time translating API documentation examples
  • Avoid syntax errors in manual translation
  • Learn how cURL maps to different HTTP clients
  • Quickly prototype API integrations
  • Convert complex requests with multiple headers
  • Works with any REST API cURL example

How to Convert cURL

  1. 1Paste your cURL command in the left panel
  2. 2Select the target language (Fetch, Axios, or Python)
  3. 3View the converted code in the right panel instantly
  4. 4Copy the result with the copy button
  5. 5Paste into your project and adjust as needed
  6. 6Test the converted code in your application

Understanding cURL Options

-X or --request: HTTP method (GET, POST, PUT, DELETE). -H or --header: request header (e.g. -H 'Content-Type: application/json'). -d or --data: request body for POST/PUT. --data-raw: raw request body. -u or --user: basic authentication (user:password). -k or --insecure: skip SSL verification. -L or --location: follow redirects. This tool handles the most common options (-X, -H, -d) which cover 90% of API documentation examples.

What to Check After Conversion

After converting, confirm that JSON bodies are valid, authorization headers are still correct, and the method matches the API documentation. Some APIs need cookies, query parameters, multipart forms, redirects, or special TLS settings that are not represented in a simple generated snippet. Treat the output as a starting point and test it in your real application environment.

Fetch vs Axios vs Python Requests

Fetch is built into modern browsers and recent Node.js versions, making it good for lightweight JavaScript examples. Axios is popular in JavaScript apps that want interceptors, defaults, and consistent response handling. Python requests is commonly used for scripts, backend automation, and quick API experiments. Choose the output format that matches where the request will actually run.

Frequently Asked Questions

Does it support all cURL options?

It supports the most common options: -X (method), -H (headers), -d/--data (body). Complex options may not be fully parsed.

Can I convert to PHP?

PHP support may be added in a future update. Currently the tool supports JavaScript Fetch, Axios, and Python requests.

What is the difference between Fetch and Axios?

Fetch is built into modern browsers and Node.js 18+. Axios is a third-party library with more features like request interceptors and automatic JSON parsing.

How do I handle authentication in the converted code?

Authentication headers (like Authorization: Bearer token) are automatically included in the converted code if present in the original cURL command.

Can I convert multiple cURL commands at once?

Currently one command at a time is supported. Batch conversion may be added in a future update.

Can I use the output commercially?

In most cases, yes. You can use the generated or processed output in personal and commercial projects, but legal, financial, medical, or security-sensitive work should still be reviewed by a qualified person.

Is my input stored?

The tool is built for quick browser workflows. You should still avoid entering highly sensitive data unless the specific tool clearly states how the data is handled.
