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.
