🔒 All processing happens in your browser. Your JSON is never uploaded or sent to any server.

How to Use

  1. Paste a JSON object (typically an API response) into the left pane.
  2. Optionally set the Schema Variable Name — this becomes the name of the outermost Zod schema constant.
  3. Click Convert to generate the Zod schema with the import { z } from "zod" import included.
  4. Click Copy Result and paste into your TypeScript project. Refine the schema by adding validators as needed.
