Thanks! Looks like this is good to go

Thanks! Hope the code is clear for you. I feel like we have come a long way since #702.
Also happy you stuck with me on this one.

I feel like you are starting to like wb_dims() (almost) as much as I do🎉 ?

[JanMarvin]

It’s perfectly fine! And yes, we sure have. And if I think of dims I always think about wb_dims(). Just like color and wb_color().

The only thing I’m constantly sad about is that we’re still not able to select dims as freely as I want. I like to see a system where it’s possible to have various independent cells. Like “A1:B2,A3:C3“, but unfortunately that’s not yet possible. dims_to_df() would need changes and probably all related functions as well.

But we’ll see, Rome wasn’t built in a day. Soon we’ll see the 1000th issue, PR or discussion. Wouldn’t imagine that when I started

I agree, but at least we have a solid foundation, we know we can trust the results, and won't be able worried to break existing code when we extend it.
