Frequently Asked Questions.

Everything you need to know about using this JSON tool safely and efficiently.

Does the converter handle nested objects and arrays?
Yes. Nested objects are automatically extracted into distinct, reusable TypeScript interfaces with accurate parent-child type relations.
Are optional fields and union types supported?
When array elements contain varying schemas, the generator infers union types or optional properties where appropriate.
