Uhh...the error pretty much says it all. Excel does not allow you to have > 255 columns. We enforce that at runtime so that you don't generate XLS files that Excel can't load.

Hi,
While generating an excel sheet using POI I'm getting the following error.
Its a huge file with 386 columns. Kindly help.

java.lang.RuntimeException: You cannot have more than 255 columns in a given row (IV). Because Excel can't handle it

Thanks n Regards,
Ruchira
