I\'ve got simple code to copy files with xlutils, xlrd, xlwt (downloaded new libraries from python-excel.org) with not loosing formatting. I\'ve got an error as below:
According to this thread the flag
formatting_info=True
is only working for xls-files, but not for xlsx yet (Version xlrd-0.8.0).
As a workaround you could convert the workbook to xls using Excel or OpenOffice.
It seems that a commandline conversion from xlsx to xls is possible using Unoconv on Linux, Windows and MacOSX.
