Type generation

JSON to Zod.

Generate a z.object(...) schema from any JSON document, with an inferred TypeScript type for free. Runs locally, nothing uploaded.

Local · No upload · No size limit on opening · Apache-2.0

Pandia turns a JSON document into a Zod z.object(...) schema you can use for runtime validation — plus a z.infer type alias so you get a static TypeScript type from the same source of truth.

Example

Input JSON:

{
  "id": 42,
  "name": "Ada",
  "active": true,
  "tags": ["admin", "early"]
}

Zod output:

import { z } from "zod";

export const Root = z.object({
  id: z.number(),
  name: z.string(),
  active: z.boolean(),
  tags: z.array(z.string()),
});

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

What you get

  • A z.object(...) schema for runtime validation.
  • A matching z.infer<typeof Root> TypeScript type.
  • Optional and nullable fields inferred from the data.
  • Great for validating API responses against real payloads.

It’s the same engine behind Pandia’s type generation — opinionated, deterministic, and built to run on files far too large for an online converter.

Frequently asked questions

How do I generate a Zod schema from JSON?

Open the Types panel in Pandia, choose Zod, and copy the z.object(...) schema into your project.

Do I get a TypeScript type too?

Yes. The output includes a z.infer type alias, so the schema and the static type stay in sync.

Does it work offline and on large files?

Yes — generation is fully local with no upload, and Pandia handles multi-gigabyte JSON without freezing.
