I tried this out when it was mentioned a few weeks ago[1].

It's pretty neat but does have a number of bugs. The packaged version also doesn't have xls support compiled in (at least on Fedora) which is unfortunate, though building is fairly easy[2].

I love the idea of it though, so I'm really hoping these issues get ironed out! I'm happy to help contribute if maintainers are willing.
