⚡ Recursive Parsing

Handles deeply nested objects and arrays. Each nested object becomes its own named interface, preserving full type hierarchy.

🎯 Smart Type Inference

Automatically detects string, number, boolean, null, arrays, and nested objects from your data.

🔧 Zero Dependencies

Runs entirely in your browser. No data is sent to any server. Fast, private, and works offline after first load.
