100% Client-Side Parsing

cURL string decomposition, regex evaluation, and code snippet generation run entirely in your local browser sandbox.

Cross-Language Transpilation

Instantly converts bash flags into structured JSON, modern ES6 async fetch calls, Axios config objects, and Python requests scripts.

Sub-Millisecond Execution

Zero network latency round-trips. Type or paste arbitrary complex multi-line terminal commands with instantaneous live updates.

Technical Reference & Architecture Guide

cURL to JSON & Multi-Language Code Converter Guide — Reference Guide

Parse raw cURL commands into structured JSON, JavaScript Fetch, Axios, and Python requests locally with zero server transmission.

Key Parameters & Controls

HTTP Methodstring

Derived from -X, --request, or implicit payload flags (-d, --data).

Target URL & Querystring

Sanitized target endpoint with extracted query string key-values.

Headers MapRecord<string, string>

Normalized HTTP headers parsed from multiple -H and --header options.

Body Payloadobject | string

Automatically decoded JSON object or raw body content from -d / --data / --data-raw.

Pro Tips & Best Practices

Common Gotchas & Troubleshooting

Wrap arguments in standard single quotes or collapse newlines before pasting into the analyzer.

Replace local filesystem paths with simulated sample payloads since browser execution cannot access disk files.

Frequently Asked Questions

Are my API keys or authentication headers sent to any server?▼

Never. All regex parsing, URL decomposition, and code generation run 100% locally in your browser memory.

Does it support GraphQL cURL queries?▼

Yes, GraphQL queries formatted inside JSON bodies are parsed and extracted cleanly into query and variables fields.

How are cookies handled from -b / --cookie flags?▼

Cookie strings are automatically parsed and structured into the request headers map as Cookie: key=val.

Can I convert the parsed request to Axios or Fetch with one click?▼

Yes, use the code tabs above the output to toggle between JavaScript Fetch, Axios, and Python Requests snippets.
