Convert XLS Files on Mac

What is XLS?
XLS is Microsoft Excel's legacy binary spreadsheet format, the default from Excel 97 through 2003 before XLSX replaced it. Based on the BIFF binary structure, XLS files still surface when working with older documents and systems that export in the classic Excel format.
XLS files are stored uncompressed. Nothing is lost to encoding, though they can take more disk space than compressed formats.
XLS was developed by Microsoft.
