Sounds like we're lacking table formatting on Lemmy! Definitely need to put a request in for that.
Looks like this is a good alternative to Google docs. No log in required for people to view or create the spreadsheet. You can import your spreadsheet straight into it as well. I've not fully looked into them so I may have missed some security issues, but the no login required feature caught my eye!
Nextcloud has a Collabora plugin for those with their own domain and hosting. Basically Libre Office cloud.
