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.
MKV at a glance
MKV
Convert to MKV when you need multiple tracks, subtitle support, chaptering, or less common codec combinations in a single container.
It is ideal for archival masters, media-library organisation, multilingual releases, and technical video handoff.
For mainstream web playback and easiest consumer sharing, MP4 is usually simpler.
