.xlsx is the default Office Open XML workbook format used by Microsoft Excel starting with Office 2007 and remains the standard in current versions. The .xls extension represents the older binary Excel format (Excel 97-2003), .csv is a plain-text comma-separated values file that many programs-including Excel-can open, and .ods belongs to the OpenDocument spreadsheet format used by LibreOffice and similar suites; none of these three identifies the modern native Excel workbook format.
