AZW3 at a glance
AZW3
Convert to AZW3 when producing an ebook for Kindle devices or Amazon-oriented reading environments, especially when the content benefits from more modern ebook styling than older AZW offers.
It is a good target for polished Kindle-ready releases and managed personal ebook libraries.
For neutral authoring and exchange, EPUB remains the more portable source format.
CSV at a glance
CSV
Convert to CSV when data needs to move between tools rather than preserve layout.
It is the standard target for database exports, spreadsheet imports, mailing-list uploads, analytics extracts, and one-time migrations into other business systems.
Use CSV when recipients need a simple table they can open anywhere or ingest programmatically, and avoid it when formulas, multiple sheets, cell formatting, comments, or strong typing need to survive the conversion.
CSV is best when interoperability and machine-readability matter more than presentation.
