JSON to TypeScript

It analyzes your JSON data and generates corresponding TypeScript type definitions, including interfaces and type aliases with proper typing for all nested structures.

Interfaces are extendable and better for object shapes, while type aliases can represent unions, intersections, and primitives. Both work similarly for simple objects.

Yes, the converter recursively processes nested objects and generates separate named interfaces for each nested structure, named after their parent key.

Mixed-type arrays generate union types (e.g., string | number). Arrays of objects with a common schema generate a single interface for the element type.
