JSON to Zod Schema
Generate Zod validation schemas from JSON samples. The AI creates type-safe schemas with appropriate validators, constraints, optional fields, and exports the inferred TypeScript type — ready to use in your Next.js, tRPC, or React Hook Form setup.
JSON to Zod converts a JSON sample into a Zod schema (z.object({ ... })) with proper validators, optional fields, and an exported z.infer<> TypeScript type — ready for form validation, API parsing, or runtime type checking.

Frequently Asked Questions
What Zod validators does it generate?
It uses z.string(), z.number(), z.boolean(), z.array(), z.object(), z.null(), z.optional(), and z.union() as appropriate based on the JSON values.
Does it export TypeScript types?
Yes. Each schema includes export type MyType = z.infer<typeof MySchema> so you get runtime validation and static typing in one.
Can I customise the generated schema?
Ask for constraints in your description: 'add min/max to string fields', 'mark email fields with z.string().email()', etc.
Does it work for nested objects?
Yes. Nested objects become nested z.object() schemas, and arrays become z.array() with the correct element type.
