Not that I've heard of. I saw a Java component set that would do most of what Excel could, and presumably save spreadsheets in an Excel compatible form. I've never seen the same for Word though. The problem is that Microsoft changes the "doc" format fairly frequently. The cynical among us might claim they do this in order to protect their monopoly on Word. Other companies make word processors that understand the
doc format, only to have it changed on them a few months later. A Java component would face the same problem. The annoying thing is, people send me Word docs all the time, and unless my version of Word is as up-to-date as theirs, I can't read it.
