That's not an Excel problem. That's a problem with using Google's shitty, half-baked, bloated facsimile of Excel.

I personally would rather build an Excel sheet (in actual Excel) than a simple web app. In fact, I believe a double digit percentage of SaaS startups would be strictly more useful to their users if they came in the form of a downloadable Excel sheet instead of the bullshit web SPA thing. But of course, selling something useful for the customer is not how you make money today.
