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.
