Which JSON Schema specifications are supported?

This converter supports JSON Schema Draft-04, Draft-07, and Draft 2020-12 specifications, accurately translating primitive types, nested objects, array items, enum definitions, and optionality.

How does the converter handle optional vs required properties?

Properties listed in the 'required' array are rendered as mandatory fields, while all other properties are marked with optional question mark syntax (?) in TypeScript and .optional() modifiers in Zod.

Is my proprietary JSON schema uploaded to external servers?

No. The entire conversion AST engine executes 100% in your browser using local JavaScript AST parsers. Your data models and schema definitions never leave your machine.

Can I generate recursive or circular schema definitions?

Yes, the parser resolves referenced definitions ($ref) and nested child types cleanly into distinct exported TypeScript interfaces.
