Help me write quiz questions on the theme of Excel

Hello everyone ! I hope you guys are doing great and i hope my post fits here.

With my friends we like to organize events for each other. I am organizing some kind of quiz/challenge where each of the four of them gave me in private a personal theme in which they think they have an extensive knowledge. The themes are : Harry Potter, Martial Arts, Greek Mythology and Excel !

As part of the quiz i want to organize a challenge called the "Matrix" where i would have a question for each possible pair of topic (Harry Potter X Martial Arts, Harry Potter X Greek Mythology etc.)

The thing is i have a very hard time coming up with fun & relevant question for Excel. Do you guys have any idea of question to ask for : Excel X Harry Potter, Excel X Greek Mythology & Excel X Martial Arts ?
