What is a cURL parser?

A cURL parser takes a terminal-style cURL command and converts it into a structured HTTP request view.

It is useful for debugging API calls, understanding copied commands from docs or DevTools, extracting headers and body payloads, and converting cURL into fetch() or Axios code.

How to use the cURL Parser

Paste a full cURL command into the input field.
Click Parse to extract the request method, URL, headers, query parameters, and body.
Review the parsed JSON output.
Copy the generated fetch() or Axios code if you need it in your app.

Tips

Commands copied from terminal often include backslashes and line breaks — this tool normalizes them automatically.
If a cURL command contains -d or --data, the request method is usually treated as POST unless -X sets a different one.
Authorization headers and basic auth flags are summarized for easier inspection.
This tool is best for common HTTP cURL commands and debugging workflows.

Request review checklist

Remove secrets before sharing

Authorization headers, cookies, API keys, and basic auth values should be redacted before sending parsed output to another person.

Confirm the method

Some cURL commands imply POST when data is present. Check the final method before converting the request into application code.

Check body format

JSON, form data, and raw bodies need different headers and parsing behavior in server-side handlers.

Verify generated code

Generated fetch, Axios, Python, or Ruby snippets are starting points. Review timeouts, retries, credentials, and error handling.

Method and body

Confirm the HTTP method matches the payload and distinguish JSON, form data, multipart uploads, and raw request bodies.

Headers

Review Content-Type, Accept, authorization, idempotency, and vendor headers that can change how the server handles the request.

Shell expansion

Watch for quotes, variables, file references, and escaped characters whose meaning depends on the shell that created the command.

Secret removal

Replace bearer tokens, cookies, API keys, and signed URLs before sharing parsed requests in tickets, logs, or documentation.

Parse curl -X POST -H 'Content-Type: application/json' --data '{"ok":true}' https://api.example.test to review method, headers, body, and URL separately.
