My dad is running a spreadsheet in Office on his 2011 iMac that he originally wrote in VisiCalc on the Apple II+ in 1980. There are ways, or at least used to be. I believe his path was the following:
VisiCalc 13-sector diskette -> ProDOS file system hard disk -> Macintosh Performa 525 with ProDOS system extensions -> ClarisWorks 4 (could read VisiCalc documents -> Excel 5 -> Office v.X on Mac OS X 10.3 -> Office:Mac 2011 on Mac OS X 10.7.x
Sure, there's a missing link in there, but we were moving that stuff around when those things were current products over the last 20 years.
