Excel online is not a pleasant experience. Google sheets is much better. Row zero seems way better.

Excel is really great if you don't have too much data. We love Excel! But we just had too much data for it, so we built the solution we wanted.

We can handle 100x more data than Excel (online or desktop), Google Sheets, etc.

Excel online still struggles to work with databases well. In classic disruption theory (the real theory by Clayton, not the TechCrunch 'disruption'), these products have less features but are simpler and can win the low-end of the market then move up-market over time.

I suspect that people glued to M365 ecosystem are the LAST ones to consider leaving Excel online, but that's okay!

Excel online is a crippled piece of shit though.
