About JSON to Go Converter
The JSON to Go converter uses `quicktype-core` with `just-types-and-package: true` to generate Go struct definitions with proper `json:` tags. Output is post-processed by gofmt via WASM for canonical Go formatting. The UML class diagram panel shows the inferred struct hierarchy.

Frequently Asked Questions
QAre json: struct tags included?
Yes — every field includes a json:"fieldName" tag derived from the JSON key name.
QIs my data sent to a server?
No. quicktype-core and gofmt WASM run in a Web Worker inside your browser.
