Few home users buy MS office(cost) however, millions use the free MS Works that comes with computer purchase or low cost. The Office spreadsheet (xls) files can be viewed with free MS viewer, but I haven't found a smart phone app that can view the Works .xlr files. Multiple steps need to be taken to convert .xlr to .xls so they can be viewed elsewhere(usually with formatting problems) . Since home users range in the millions with MSWorks as opposed to MSOffice, why haven't I seen more(or ANY) about opening .xlr files in an app or just simple program. Is it a proprietary thing with MS?
