The problem is more that it's insanly overpowered, while aiming for convenience out of the box. An "Excel Pro"-Version which takes away all the convenience and gives the user the power to configure the power pinpointet to their task might be a better solution. Funny part is, most of those things are already configurable now, but users are not educated enough about their tools to actually do it.

Excel allows people to maintain data all over the place. From golf league data to job actual data compared to estimates to so much more. And, excel is accessible enough that tens of millions (or maybe more) of people do it.
