Attempting to load the attached file causes exception

Probably the first reason is that the file has macros, and the second is that the spreadsheet 'Cashflow' has graphs. I can only load the file if I save it as xlsx, and remove the spreadsheet 'cashflow'.

I do not need or want the macros, but they may be part of any file I upload, as may be the spreadsheets. I wish to extract information from some of the other sheets. I would prefer that the system loads what it can load.

the instruction executed:

final Book book = Importers.getImporter().imports(new File(tempPath), "Imported");
