JSON to Zod — Generate Runtime Validation Schemas & TypeScript Types

TypeScript interfaces validate code at compile time, but Zod schemas validate real API responses at runtime. Paste any JSON object here and get a complete z.object({...}) schema along with exported z.infer<typeof ...> types.

The output handles nested object schemas, primitive types (z.string(), z.number(), z.boolean()), optional fields with .optional() or .nullable(), and array schemas with z.array(...).

❓ Frequently Asked Questions

Is processing on json-to-zod.html private and secure?

Yes. All JSON processing, parsing, and code generation happen 100% locally inside your browser sandbox. No server roundtrips or third-party tracking occur.

Is JSON Workbench free to use for JSON to TypeScript Zod Schema Generator Online?

Yes, JSON Workbench is completely free for commercial and personal developer use with zero registration or payload limits.

Can I copy or download the generated output?

Yes! You can instantly copy the output code to your clipboard or download it as a structured file.
