I agree. However, so many of my use cases include a one-to-many relationship that I was outgrowing excel/sheets too quickly. Once a project added a VLOOKUP, it hit an inflection point in complexity.
I spun up a local Grist instance in my org, using SAML with our org's email authentication. It's intuitive enough that I've replaced a few shared spreadsheets with it (now with rowwise permissions) and powerful enough that I've also replaced a few internal CRUD apps.
