Reverse conversion

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.

HDR at a glance

HDR

Convert to HDR when you need scene-referred high-dynamic-range image data for rendering, environment lighting, or technical HDR processing.
