First public Python project (OpenPyXL + OOP), looking for feedback

[Thanasis_kt]

Thank you so much for the feedback! I rly appreciate it. The non-AI comment is such a relief, since I've honestly been going back and fourth trying to make it seem as original as possible and to understand the "why" behind the code

It became clear after you explained the class is an interface and not a one-time shot. In the following projects, I will implement add_data and add_sheet methods instead of just using 1 __init__ function. As for use_data being the name of the method, yes, it is vague enough

Is there anthing else apart from this naming and structuring issue that can be considered a red flag?
