Microsoft Symbolic Link File (SYLK) is a file type used for exchanging information between applications in a Microsoft Windows environment. It is a plain text file format consisting of lines of text with fields separated by semicolons. SYLK files typically contain data such as spreadsheet values, labels, and formulas.
An XLS file is a spreadsheet file created by Microsoft Excel or exported by another spreadsheet program, such as OpenOffice Calc or Apple Numbers. It contains one or more worksheets, which store and display data in a table format. XLS files may also store mathematical functions, charts, styles, and formatting.
