About XLS
XLS is the older binary spreadsheet format used by Excel versions before 2007.
Still needed when working with legacy systems or older software that doesn't support XLSX.
XLS files are limited to 65,536 rows and 256 columns, a fraction of the modern XLSX capacity.
💡 The XLS binary format dates back to 1987, making it older than the World Wide Web itself.
