File extensions are related to the file format, which is a computer programming term that specifies how information is coded for storage in a computer file. In the case of Excel, the current default file extension is XLSX and has been since Excel 2007. Prior to that, the default file extension was XLS. The difference between the two - besides the addition of the second X - is that XLSX is a XML-based open file format, while XLS is a proprietary Microsoft format.
The XLS format is the same format as earlier versions. When you use this format, you are restricted to 256 columns and 65,536 rows. When you save an Excel 2007 or Excel 2010 workbook in XLS format, Excel runs a compatibility check.
