What is a .xls file?
XLS is the legacy Microsoft Excel format using the binary BIFF structure inside an OLE2 compound file, superseded by XLSX in 2007. It stores worksheets, formulas, and formatting in a binary layout rather than XML. It remains common in older systems and exports.
How to use this file
Use an example XLS to test legacy binary spreadsheet parsing, OLE2 compound-file handling, and converters that upgrade older workbooks to XLSX or CSV.
