What is a cURL Converter?

A cURL converter is a developer utility that automatically parses command-line curl HTTP requests and translates them into native code snippets (like Python requests, Node fetch, Go) or API specifications (like OpenAPI 3.1 YAML and Postman Collections). It also supports reverse-parsing OpenAPI specifications back into runnable cURL commands.

How to Use This cURL Converter

  1. Select your desired mode: "cURL → Targets" or "OpenAPI → cURL Examples".
  2. Paste your raw cURL string or OpenAPI YAML/JSON into the input box.
  3. The tool instantly parses your input, mapping headers, payloads, and parameters.
  4. Scroll to the output panels to copy or download your generated code snippets, Postman collections, or OpenAPI blocks.

Examples / Use Cases

Use Case 1: Browser Network Tab to Python

Right-click a failing network request in Chrome DevTools, select "Copy as cURL", paste it into the converter, and instantly get a reproducible `requests.post()` script in Python to debug the API locally.

Use Case 2: cURL to OpenAPI

When writing documentation, paste a cURL command with a JSON body into the tool. It automatically generates a valid OpenAPI 3.1 schema block for that endpoint, inferring string, number, and object property types from the JSON.

Advantages and Limitations

Privacy & Security

This tool works entirely locally in your browser using client-side JavaScript. Your cURL commands, API keys, Bearer tokens, and OpenAPI specifications are never sent to external servers.

Frequently Asked Questions

Is my parsed cURL data kept secure? ▼

Yes, absolutely. The conversion process is run 100% locally on your computer inside your web browser. Absolutely no server uploads, tracker databases, or logs exist. Your sensitive bearer keys, authorization tokens, and payloads never leave your browser window.

How does JSON schema mapping work? ▼

When translating cURL commands that contain JSON data bodies (via -d or --json), the converter parses the payload object, runs a type inference engine across the keys (detecting booleans, numbers, null, objects, and arrays), and automatically generates complete properties blocks for OpenAPI 3.1 YAML.
