JSON to Zod Schema

Generate a runtime-safe Zod schema from any JSON object.

JSON Input

Zod Schema (TypeScript)

import { z } from "zod";

const schema = z.object({
  "id": z.number().int(),
  "name": z.string(),
  "email": z.string(),
  "active": z.boolean(),
  "score": z.number(),
  "tags": z.array(z.string()),
  "address": z.object({
    "city": z.string(),
    "zip": z.string(),
  }),
});

type Schema = z.infer<typeof schema>;

export { schema, type Schema };

What is Zod?

Zod is a TypeScript-first schema validation library. Unlike TypeScript types (which are erased at runtime), a Zod schema validates data at runtime — perfect for API responses, form inputs, and environment variables. This tool infers a Zod schema from a JSON example: objects become z.object, arrays become z.array, strings/numbers/booleans map to their Zod equivalents, and null values become z.null().

Private & free — this tool runs entirely in your browser.
