RB in sintesi
RB
Convert to RB only when preserving or reproducing legacy Rocket eBook collections or working inside an archival reconstruction workflow.
In normal publishing practice, RB content is usually migrated into EPUB or Kindle-oriented formats.
It is a heritage compatibility target, not a modern distribution format.
NUMBERS in sintesi
NUMBERS
Convert to NUMBERS when the recipient is expected to work further in Apple Numbers, especially for schedules, lightweight financial sheets, classroom materials, or visually arranged tables in Mac- and iPad-based workflows.
It is useful when the Apple editing experience matters more than cross-platform ubiquity.
For broad office interoperability, XLSX is usually the safer spreadsheet target.
