Frequently Asked Questions
What is Zod?
Zod is a TypeScript-first schema declaration and validation library. It lets you define schemas and validate data at runtime while automatically inferring TypeScript types.
Does it generate TypeScript types?
Yes. Every generated schema includes a z.infer() type alias, so you get both runtime validation and static typing from a single source of truth.
Can it handle nested objects and arrays?
Yes. Nested objects are extracted into named schemas, and arrays with mixed element types are represented using z.union().
Does this tool send my data anywhere?
No. All conversion happens 100% in your browser. No JSON data is ever sent to a server or stored.
