Verified Utility

JSON to Types & Schema Converter transforms raw API responses, database records, and mock JSON payloads into strongly typed definitions across TypeScript, Zod, Python Pydantic, Go, and Rust. It recursively inspects nested data structures, resolves object arrays, and outputs type-safe models.

How it works

Paste JSON Payload

Paste your raw JSON response or select an account, order, or paginated preset.

Select Schema Type

Choose from TypeScript interface/type, Zod schema, Pydantic, Go struct, Rust Serde, or JSON Schema.

Copy Type Definitions

Copy clean, compiler-ready type models with appropriate field naming and type tags.
