XLS files are Excel workbook files created in Excel 97 or Excel 2003. The 2007, 2010 and 2013 versions of the program use the XLSX format by default to save workbooks, but can also use the XLS format. You can edit XLS spreadsheets you received from your customers or employees in Excel 2013 and save them as XLSX or XLS files.
What is a XLSX file? Files with the .xlsx extension are Microsoft Excel files that have been created using Microsoft Excel versions 2007 and later. Previous versions of Excel that were created prior to 2007 saved these spreadsheet documents in .xls format. The 2007 and later versions of Excel use the Office Open XML Format, creating the .xlsx extension.
