That's arguably the goal of [Pluto.jl](https://github.com/fonsp/Pluto.jl). It's a (Julia-specific) reactive notebook that automatically updates all affected cells and has no hidden state.

That looks so good that I am thinking about learning Julia.

Well then I would like to through this your way. https://mitmath.github.io/18S191/Fall20/

Thx I will check that.

Ooh that's really good, thank you for sharing!

Please no. Excel is great when it stays within its lane and use case and doesn't try to be everything. Jupyter is okay-ish is some places but in general is way overused. Mixing them together would be a move in the wrong direction and a bit of a mess.

If you mean to retire VB in favor of Python for writing macros, I'm all for it. Not much Jupyter though

There's been a few projects in this space (PySpread is the first that jumps to mind), but also, not too long ago (last year maybe?), MS was investigating making Python a first-class inhabitant of Excel, so might already be in the pipeline.

It's already been done https://www.youtube.com/watch?v=Od-1cEac9U4&feature=emb_titl...

Oh no.
