Zod is a TypeScript-first schema validation library. It defines data shapes with runtime validation, type inference, and excellent error messages. Widely used in Next.js and React projects.
Paste sample JSON and the tool analyzes its structure to generate corresponding Zod schemas. Objects become z.object(), arrays become z.array(), strings/numbers/booleans map to z.string()/z.number()/z.boolean().
Yes. Nested objects generate nested z.object() schemas. Arrays of objects create z.array(z.object({...})) with the correct inner structure.
Some generators offer options like optional vs required fields, nullable types, and custom validation messages.
No. All generation happens locally in your browser. No JSON data is sent to any server.
