JSON → Zod

Generate a Zod schema from a JSON sample.

Private by design. Your input never leaves this browser. Conversions run locally on your device.

What this tool handles

  • Emits a Zod schema, with or without the import line.
  • Whole numbers become z.number().int() when integer inference is on.
  • Nested objects become nested z.object() calls.
  • The schema describes the sample you paste; it is not inferred from a wider dataset.

Example

JSON sample

{"id":1,"name":"Ada","active":true}

Zod schema

import { z } from 'zod';

export const RootSchema = z.object({
  id: z.number().int(),
  name: z.string(),
  active: z.boolean(),
});

export type Root = z.infer<typeof RootSchema>;
