Zod is a TypeScript-first schema validation library. A Zod schema defines the shape of your data and validates it at runtime — catching type errors before they reach production. This tool generates that schema from a JSON sample.
Nested objects become nested z.object() calls. Arrays become z.array() with the correct inner type inferred from the first element. Null values become z.null(). Empty arrays become z.array(z.unknown()).
Yes. The generated schema is valid TypeScript code. Just add import { z } from "zod"; at the top of your file and paste the schema.
