What to Know About Excel to CSV

  • Both modern .xlsx and legacy .xls workbooks are supported.
  • The first worksheet is converted, including the header row.
  • The output is UTF-8 encoded so accents and non-Latin text survive the round trip.
  • For whole-workbook or multi-sheet export use the offline Data File Converter.
