Power Apps Responsive Header and Footer Components + Debugging

hey shane, can you please guide me on how to just draw a textbox in powerapp and then import the text from a excel data table so it will show up? I want to make a survey app and already have all the questions and answers in a table in excel, so it would be nice if Im able to import this text, so I dont have to write down all the questions in powerapp again.
I only see those "make an app with excel source" videos, but I cannot see how to simply get a text of e.g. A1 in excel onto my text box. Any help is appreciated.

Great video Shane, thank you!

Thank you Shane for this great video

This is an excellent video, Shane. I got a lot of "light bulb" moments on building Responsive Apps. Was there suppose to be a part 3? If so, please point me to that one. Thanks again for sharing.

Where is the 3rd part of this series?

I'm glad that I'm not the only one who has redraw issues like at 28.04.
