XLSX and XLS files are Microsoft Excel Spreadsheets commonly used to store financial data and to create mathematical models. These files store data in worksheets that contain cells arranged as a grid of rows and columns. Excel spreadsheets may also contain charts, mathematical functions, and various kinds of cell formatting. Spreadsheets are often used in business contexts to store financial data and to perform mathematical computations.
There are differences in the XLSX and XLS formats created by Excel. While XLS files use a proprietary binary format, XLSX files use a newer file format referred to as Open XML. The XLS extension is used by Microsoft Excel 2003 and earlier and the XLSX extension is used by Microsoft Excel 2007 and later.
