> The best of both worlds, IMO, is a spreadsheet for data visibility, and a program for transformation visibility.

Having used Excel way more than I expected last year, I agree with this. Transforming data one time to explore it on Excel is really easy and nice. On the other hand, trying to automate the steps that other people do manually is often not so nice and easy and I'd love to be able to use something else than VBA, something like pandas for exemple.

As an aside, I've been looking for a tool to handle spreadsheets with a few millions rows and that can be used by people without too much experience with programming. Do you think Mito would fit this use case?
