JSON to Zod Schema Generator

Paste any JSON object and get a ready-to-use Zod schema with an auto-inferred TypeScript type. The generator handles nested objects, arrays, null values, integers vs floats, and optional strict mode — all in your browser.

Frequently Asked Questions

What is Zod?
Zod is a TypeScript-first schema declaration and validation library. It lets you define schemas for your data and automatically infer TypeScript types from them.
What does strict mode do?
Strict mode adds .strict() to every z.object(), which causes Zod to reject any object containing keys not defined in the schema. It also generates z.number().int() for integer values.
Does this handle nested objects and arrays?
Yes. The generator recurses into nested objects and arrays up to 8 levels deep, creating named Zod object schemas at each level.
Is my JSON sent to a server?
No. All generation is performed with JavaScript running in your browser. Your data never leaves your device.
