Files that contain the .xlr file extension are commonly used by the Microsoft Works productivity suite. The .xlr file extension is used when creating charts and spreadsheets within the Microsoft Works spreadsheet application. The chart and spreadsheet files that are saved with the Works application are saved with the .xlr file extension.
Microsoft Works is similar to Microsoft Office, but the applications that are provided in the Works suite do not have as much functionality or as many features as the applications that are included with Microsoft Office software suite, making the Works applications more common for personal use than for business use.
