What is an XLR file?
An XLR file is a spreadsheet or chart created with versions 6-9 of Microsoft Works, a popular productivity suite. It stores data in cells that are organized in a grid consisting of rows and columns.
Works is the entry-level productivity suite developed by Microsoft. It contains similar programs to Microsoft Office, but with limited features.
NOTE: XLR files created with Works 8 or later are also recognized by Microsoft Excel.
