Input JSON

Zod Schema

import { z } from "zod";

export const schema = z.object({
  "name": z.string(),
  "isAwesome": z.boolean(),
  "visitors": z.number(),
  "tags": z.array(z.string()),
  "metadata": z.object({
  "createdAt": z.string(),
}),
});

export type SchemaType = z.infer<typeof schema>;

Why use Zod for JSON Validation?

When fetching data from an external API, TypeScript's static typing isn't enough to guarantee safety at runtime. If an API returns unexpected data (like a string instead of a number), your app might crash.

Zod solves this by combining static type inference with strict runtime validation. By converting your expected JSON responses into Zod schemas, you ensure your app fails gracefully and catches malformed data at the boundary.

How does this tool work?

This tool recursively parses your JSON object and infers the primitive types (`string`, `number`, `boolean`, `null`). It then builds the corresponding `z.object()` and `z.array()` definitions.

Privacy First

Your JSON data never leaves your browser. This conversion runs entirely client-side, making it safe for pasting sensitive API responses or proprietary data structures.
