Adam,
Yes, the new excel can handle more than 256 columns.

But, the IDV calls org.apache.poi.hssf.usermodel to create columns and the 
limitation for this usermodel is still the same. The solution is to switch to 
use org.apache.poi.xssf.usermodel, and this will involve other consideration. 
We will discuss this in our developer meeting and I can not promise anything at 
this moment.

If you still have Java heap space issue, please try the nightly release.
