As it's written in the Readme:
...
io = StringIO()
save_data(io, data)
...
Does not work, as the first parameter expects a string, not bytes: TypeError: string argument expected, got 'bytes'
Issue happened with pyexcel-ods 0.6.0.
Tested with pyexcel-io 0.6.6 and 0.6.7 (Which is the latest at the moment.)
Used python version: 3.11.
