FAQ
Simple by design.
Is my JSON uploaded anywhere?
No. Parsing and generation happen locally in your browser. The tool does not need an account, database, or API.
What happens with nested objects and arrays?
Nested objects are converted into additional model types. Arrays use the inferred element type where a representative element is available.
Can I use the generated code commercially?
Yes. The generated output is ordinary source code intended to be copied into your own projects.
