Understanding XLS and XLSX file formats

XLS is a file format used by Microsoft Excel for storing spreadsheet data. It was the default format for Excel files until Excel 2007. XLS files are binary files and can contain data such as numbers, text, formulas, and charts.

XLSX is the successor to the XLS format and was introduced with Microsoft Excel 2007. It is based on the Open XML format and is more efficient in terms of file size and data management. XLSX files are XML-based and can store the same types of data as XLS files but with improved performance and compatibility.
