Why convert

Why convert XLS to CSV?

CSV is the universal import format. Getting data out of a legacy workbook and into plain, portable rows is usually the first step in moving it anywhere else at all.

  • Data trapped in an old workbook needs importing into a current system.
  • A script or database needs plain rows rather than a binary workbook.
  • You are migrating off legacy spreadsheets entirely.
  • A multi-sheet workbook has to become one file per sheet.
