You can share with git. But obviously this is no real replacement for cloud based multi user spread sheet software.

To be honest I also think that if you are making heavy use of cloud based spread sheet software you have a 100% chance of being a drain on your organization and society as a whole, so I can't really count those missing features as a big downside.

How about for just personal (family/friends) usage?

I would tend to agree spreadsheets are a crutch in larger orgs, however they're best deployed as a prototype tool IMO.

There's plenty of room for > 1 and < 5 (write-access) person operations where cloud based xlsx sharing just makes far more sense than some expensive/excessive enterprise tools.

It appears to support XLSX, so for certain level of sharing it should work.

I suppose you could share using tmux or screen.

And my next question would be can this software handle concurrent writes?

If it could, that'd be an excellent solution.
