Visual problem with xlsx file with openpyfile with checkbox

Maybe someone had his problem before so I'm asking for help ! I am stuck since 2 days with this visual. I don't know how to read and use checkbox with openpyxl and after all my research, I'm still stuck.

I'm ready to move to another library if this is needed !

I tried win32com.client but I had library with win32.gencache.EnsureDispatch('Excel.Application').

I tried xlwings but I had troubles with module 'xlwings' has no attribute 'Book'. (module 'xlwings' has no attribute 'Book' didn't worked.)

bad_visual

I can't believe it's that complicated !!! But actually I fail...
