How does JSON to TypeScript conversion work?

The tool parses your JSON and recursively generates TypeScript interface definitions based on the structure and types of your data.

Does it handle nested objects?

Yes. Nested objects generate separate interfaces, and arrays are typed with the correct element type.

No. All parsing and conversion happens entirely in your browser. Nothing is sent anywhere.

The tool will show a parse error with a clear message indicating where the JSON is invalid.
