Frequently Asked Questions — JSON to Go Struct
Are nested objects supported?+
Yes. Each nested object becomes a separate named struct, automatically named after its key in PascalCase.
How are json tags generated?+
The tool adds `json:"fieldName"` tags using camelCase as the JSON tag name.
What happens with null values?+
Null values become `interface{}`. Enable pointer mode to get `*interface{}` instead.
What about arrays of objects?+
Arrays of objects generate a separate struct named after the field + "Item" suffix (e.g. ItemsItem).
