XLS is a file format used by Microsoft Excel for storing spreadsheet data. It is based on the Binary Interchange File Format (BIFF) and stores information in binary format. XLS was the default file format for Excel until the release of Excel 2007 when it was replaced by the newer XLSX format, which is XML-based and has a more open structure.
XLSX is a file format used by Microsoft Excel for storing spreadsheet data. Introduced with the release of Excel 2007 as part of the Office Open XML standard, it is now the default format for creating spreadsheets using modern versions of Excel. XLSX files are XML-based and have a more open structure than the older XLS format, allowing for smaller file sizes and better recovery of information from damaged files.
