Why convert a XLSX file to CSV?

An XLSX needs a spreadsheet app to be read, and imports poorly into many tools.

A CSV imports everywhere: databases, CRMs, email tools, accounting.

What about quality?

All values are kept. To CSV, only the first sheet is exported (Morfile tells you); the separator can be adjusted.
