What does it generate?

Plain Java classes — one per object in the document — with field declarations plus getters and setters. No framework annotations are added, so the output drops into any project.

Can I set the package and root class name?

Yes. Both are editable before you convert, and the root class name is reused for the top-level object.

How are nested objects and arrays handled?

Nested objects become separate classes, and arrays of objects produce a class for the element type with a List field on the parent.

No. Generation runs entirely in the page.
