Not only is that certainly not a fact, as the sibling commenter said, I find it striking how you're seemingly purposely missing the point.

They KNOW excel, they know where which buttons are, and the business logic and price calc are done in excel. These people aren't mentally challenged as you seem to think, they will know if their excel suddenly looks differently, offered by Google instead of Microsoft and in a browser instead of a native windows app.

So if you have nothing to contribute except power user arrogance, I will no longer interact with you.
