Zod Schema Generator

Generate Zod validation schemas from JSON data. Detects emails, URLs, UUIDs, dates, integers, and nested objects automatically.

About Zod Schema Generator

  • Zod is the most popular TypeScript-first schema validation library, used with tRPC, React Hook Form, Next.js server actions, and more.
  • Format inference — detects emails, URLs, UUIDs, and ISO dates in string values and applies .email(), .url(), .uuid(), .datetime() refinements.
  • Integers — whole numbers get .int(), decimals stay as z.number().
  • .strict() — rejects objects with unknown keys at runtime, great for API input validation.
  • Coerce — uses z.coerce.string() etc. to auto-convert incoming values (useful for form data and query params).
  • Type inference — generates a z.infer<typeof schema> type alias so you get TypeScript types for free.
  • Everything runs in your browser — no data is sent over the network.
