Understanding Your Results

Parses JSON in browser memory, detects primitive types, generates nested `z.object` and `z.array` definitions, applies email/URL heuristics, and produces `z.infer` TypeScript types.

Practical Guidance & Next Steps

Zod schemas provide runtime input validation for Next.js server actions, tRPC endpoints, and React Hook Form.

What is this?

A TypeScript productivity utility that converts JSON payloads into Zod validation schemas and inferred types.

How does it work?
