JSON Schema → TypeScript / Zod

Paste a JSON Schema (draft 7 or 2020-12) to project it into a TypeScript interface tree or a Zod v4 schema. Handles $ref, oneOf / anyOf, allOf, enum, and format hints. Runs locally in your browser.

Input

Paste a JSON Schema document — the top level should be an object with type or another schema keyword.

Output target

Root name

TypeScript interface tree. Nested objects become named types; arrays of objects unwrap; allOf becomes intersection; enum becomes literal union.

TypeScript output

Paste a JSON Schema to convert. Sample button on the right loads one to try.
