Hello, I generate Excel templates using Apache POI. But, somehow, the first two sheets are grouped which causes edits in one sheet to take place in the other sheet as well. It works fine if I manually (via Excel) ungroup the sheets.
But, I do not understand why the two first sheets are grouped. I don't do anything to group them, in fact I do not even know how to group sheets using POI. Does anyone have an answer to this mystery? At the very least I would like to be able to ungroup the sheets using code (not manually). Best regards, Bengt Rodehav
