How to Open XLS Files

XLS files belong to Microsoft Excel and contain information such as graphs and financial statistics. XLS files are used from Microsoft Excel '97 to Microsoft Excel 2003. These files are often generated and sent by banks, financial institutions, employers and office workers to show financial information. You will need Microsoft Excel 2003 or Later to properly view all XLS files. Microsoft has released the Microsoft Excel Viewer to allow Windows users who do not own Microsoft Office to view these files.
