I also used Google Sheets as a datastore backend: https://github.com/adam-p/danforth-east https://github.com/adam-p/danforth-east It's a community association membership management thing, and I wanted the (non-technical) association board members to be able to easily inspect the data and do something useful with it if I moved away. It has mostly been successful, except that sometimes someone will manually edit the sheet and break something.
