VSTO to the best of my knowledge is still a thing. And you could indeed do some pretty cool stuff with it!

But it's not as easy to use as VBA, nor was it incredibly easy to work with from a development standpoint when I last tried to use it (Maybe I was doing it wrong, but I had to do a full VS install with the add-in module.)

VSTA, not VSTO. It was a .net IDE embedded in an application the same way VBA works.

Ahh. I always assmued that VSTA worked the same way as VSTO...

That makes me ask why VSTO -didn't- work more like VSTA, then. It may have improved adoption substantially...
