... seems to be an issue of some specific xlwt version, which xlwt-version do you have installed?

[trvini]

Thank you for your reply. I installed the latest version as mentioned in your install instructions' from https://pypi.org/project/xlwt-future/ .

bm@up2-2:~$ pip show xlwt-future
Name: xlwt-future
Version: 0.8.0
Summary: Library to create spreadsheet files compatible with MS Excel 97/2000/XP/2003 XLS files, on any platform, with Python 2.6 to 3.3

could you try xlwt-version 1.3.0?

[trvini]

Hello, Thanks for the tip I uninstalled the xlwt-future pip uninstall xlwt-future and I still found that xlwt version was existing so I uninstalled xlwt completely by pip uninstall xlwt. Then I reinstalled with pip3 install 'xlwt==1.3.0' Now it seems to work as below. But I still see ldf is not supported error as below. I am not sure if it has any side effect

bm@up2-2:~/canmatrix/test$ canconvert --help
ldf is not supported
Usage: canconvert [OPTIONS] INFILE OUTFILE

Hi @trvini ,

ldf is not supported just means, that you cannot import .ldf files (lin bus description). If this is not your use case - you can safely ignore this message.

The old excel-libraries (.xls) are beginning to make problems. Maybe I abandon these and will support only xlsx files in future

Thank you !
