Both formats, briefly
XLSXIN
XLSX is the workbook format Excel writes today, built on Open XML. A single file can hold many sheets along with formulas, charts, pivot tables and conditional formatting rules. Choose it when the calculations need to travel with the numbers instead of only the results.
XLSOUT
XLS is the binary workbook Excel produced up to the 2003 release. Old financial models, exported reports and line of business tools still hand them out. Current spreadsheet apps read the format, though its smaller sheet limits and missing newer features are why most people move the data across.
