Have you tried grist[0]?

It's self-hostable (and the community version is FOSS I think), and really useful in a way I find better than just a spreadsheet.

It's no good for importing complex excel things, but I've found it very useful for new work.

That actually looks kind of neat, similar to Airbase unless I'm mistaken. Thanks for the recommendation, I'll definitely check it out.
