What is Zod?

Zod is a TypeScript-first schema validation library. It lets you define schemas that validate data at runtime while providing compile-time type inference. It's widely used in Next.js, tRPC, and React Hook Form projects.

How to Use This Tool

  1. Paste your JSON object or API response on the left.
  2. The Zod schema generates instantly on the right with syntax highlighting.
  3. Click "Copy" to grab the schema and paste it into your project.

Supported Types

  • Primitives: string, number (with int detection), boolean, null
  • Objects: Nested objects with proper indentation
  • Arrays: Typed arrays based on the first element
  • Type inference: Automatically generates z.infer type

Why Use This Generator?

Writing Zod schemas by hand is tedious, especially for large API responses. This tool auto-generates the schema from a sample JSON, saving you time and reducing errors. All processing runs in your browser — your data stays private.
