The existing Excel r/w scripts in the IO package have been updated to 
allow OOXML support, too. (Not that it's my favorite spreadsheet file 
format but some people may need it - or just make use of it.)

When using native Excel 2007 + COM interface this support already 
existed; now it also works platform-independent using Java + Apache POI. 
It turned out 3 more java class jars were needed (who coined the term 
"java-itis"?), but luckily they're all open-source (Apache license).
I can only test proper OOXML support using my own Excel 97 + 
Office2007Converterpack but AFAICS it all works OK, even when 
reading/writing OOXML files from Linux using Apache POI. Hopefully some 
more people will test it and report back on proper functioning and 
reliability to me.

Apache POI's formula support still has (little) bugs. AFAICS Apache POI 
doesn't alway properly parse Excel's INDIRECT() function. As soon as 
this has been sorted out by the Apache POI folks I intend to make Apache 
POI rather than JExcelAPI the preferred Java solution for Excel 
spreadsheet file support.
