JSON to Zod Schema Generator

Paste JSON and generate a Zod schema for runtime validation. The generator supports nested objects, arrays, empty arrays, nulls, booleans, numbers, strings and practical mixed-array unions.

Inferred TypeScript Types

When enabled, the output includes a z.infer type so the same schema can drive runtime validation and TypeScript typing.

Nested JSON and Arrays

Nested objects become nested z.object schemas. Arrays infer their item schema, and mixed arrays use z.union where it can be represented cleanly.
