Conversion of xlsx files to xls file format

xlsx to xls conversion essentially describes export of newer Excel spreadsheets (.xlsx) to previously used (.xls) format, something that can be easily done with Excel and the Save as.. function. Except for Excel, any spreadsheet tool that supports Excel's formats can be used as well and same goes for various document converters. Just keep in mind that some formatting exclusive to the newer format might be lost with such conversion.
