Caveat: from a POI user just doing the basics My understanding is that rows and cells don't exist on blank sheets in POI unless you create them (CreateRow, CreateCell). My guess is that the file structure behind the spreadsheet makes a similar assumption: a cell is blank/default unless there is something (style, data, etc) attached to it. Anyway, trying to operate on a row or cell that hasn't been created sounds like an easy way to get a null pointer exception.
If you are reading an existing spreadsheet, I think you can only assume that populated cells "exist" in any POI sense. Hoping I didn't totally miss the boat, Sean R.
