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.
WMF at a glance
WMF
Convert to WMF when preserving compatibility with older Windows document workflows, embedded legacy graphics, or archive recovery tasks where that classic metafile format is still expected.
It is useful as a bridge for historical Office-era vector assets.
For contemporary vector exchange, EMF, SVG, or PDF are usually more practical.
