Do people actually install and use add-ins?

Hello!

I'm a software developer and I've been tinkering with building add-ins for Excel. Before I fully YOLO into this, I was wondering if people actually use Add-ins in the wild? I can't seem to find any statistics about install rates among users, or anything like that. How popular are add-ins generally with normal Excel users, or is it a power-user only thing?

Do people here use add-ins? What are the most useful ones you have found?

Thanks for your time!
