What JSON types are supported?

All standard JSON types are supported: objects, arrays, strings, numbers, booleans, and null. Nested objects generate nested structs, and arrays generate slice types.

Are json tags added automatically?

Yes! Every field gets a json tag matching the original JSON key name. For example, "user_id" becomes `json:"user_id"` in the struct tag.

Is my JSON data sent to any server?

No. All conversion happens entirely in your browser using JavaScript/WebAssembly. Your data never leaves your machine.

What happens with nullable fields?

JSON null values are converted to interface{} type. If a field is sometimes null in different JSON samples, consider using a pointer type (*string, *int) in your final code.

Can it handle large JSON files?

Yes, the tool handles JSON files of any size since it runs entirely in your browser. For very large files, there may be a brief delay while the struct is generated.
