About this tool

This tool turns a JSON sample into a ready-to-use Zod schema, so you can validate API responses, form data, or config at runtime instead of just typing them at compile time.

It infers nested objects, arrays, and primitive types (string, number, boolean, null) automatically, saving you from hand-writing z.object({...}) calls.

Frequently asked questions

Yes — the output includes `import { z } from "zod";` so you can paste it directly into a file.
