'Dataset' object has no attribute 'xls'

When trying to export form submissions as a Microsoft Excel file, I get an AttributeError. Other export formats work fine.
The traceback looks like this:

Did I miss something while configuring or is there somehting else going on?

You might need to install tablib extras to support 'xls'. For more information, see avryhof#8.

I'll dig into Excel and YAML support soon, but for now, there is an option to remove them from the interface.

pip install --upgrade djsngocms-forms-maintained
