FAQ
Is the JSON sent to a server?
No. The conversion happens entirely in your browser; no data is transmitted or stored online.
Can I get the TypeScript type in addition to the schema?
Yes. From the generated schema, just use z.infer<typeof mySchema> to get the matching TypeScript type.
How are arrays and nested objects handled?
They are detected automatically and translated into z.array() and nested Zod objects that mirror your example's structure.
