COM isn't hot new technology, but it works, costs $0 above and beyond Excel, and can access as much (or more) of Excel.

The reason I ask is that after a quick look, the IronSpread examples don't look too much different than accessing Excel via plain old COM. [1]

And there's even a chapter in a book [2] for accessing Excel from Python through COM.

And example code [3] for wrapping Excel COM in a Python class.

I guess put another way, my question would be what does IronSpread offer above and beyond the regular access from COM?
