JSON to Zod Schema Generator

Generate a Zod schema from JSON

Infers types from a sample payload — refine optionals and unions by hand.

import { z } from "zod";

export const userSchema = z.object({
  id: z.number().int(),
  name: z.string(),
  active: z.boolean(),
  tags: z.array(z.string()),
  profile: z.object({
    email: z.string(),
    score: z.number(),
  }),
});

export type UserSchema = z.infer<typeof userSchema>;
