JSON to types

Generate TypeScript, Zod, Go, Python and JSON Schema types from JSON.

What it does

Paste JSON and get TypeScript interfaces, Go structs, Python dataclasses, Zod schemas or JSON Schema, with nested types handled.

It reads your JSON, works out the type of every value, and writes code that describes that shape. Arrays of objects are merged, so a field that appears in only some items is marked optional, and a field that is sometimes a number and sometimes text becomes a union.

Steps

1. Paste your JSON into JSON, or press Try an example.
2. Choose the output: TypeScript, Zod, Go, Python or JSON Schema.
3. Read the generated code.
4. Press Copy code, or Download.
