Does anybody have any clue as to how I can handle this scenario? Is there
even a quick and easy way to test for a "new" or "empty" spreadsheet so
that I can at least have my code delete the sheet prior to re-creating it?
Is the a way to shuffle or re-organize sheets in a workbook? I'm stuck on
this. Please help.
Thanks in advance,
-Cliff

I don't think creating the sheet is appropriate in this scenario. I have 3
sheets in a brand new workbook. The 1st sheet has some data on it and I
need to write to the 2nd sheet leaving the 3rd sheet blank. If I do a
createSheet("Sheet2") I end up with two Sheet2's where the one I create in
POI is at the end. There is no method createSheetAt(int idx) available to
create a sheet over an existing sheet. Now if there was some easy way to
test for this condition then maybe I could delete/rewrite the sheet in
question but it would be a good solution. I'd have problems getting the new
sheet in the correct order. If you consider a workbook with these "new"
sheets intermingled and sporadically placed throughout other used sheets
then it becomes a real nightmare. What do I do?

it doesn't create extra sheets. only the space for them.
you need to create all sheets that you want,
as far as I know.
