Good point - we will move things around on the marketing site.
Google Sheets does not have pinch to zoom. Maybe Excel does on some platforms, it doesn't on 365. The only other spreadsheet I know with decent pinch to zoom support is Numbers on mac.
I'm not sure what you mean by not having it, maybe you mean something different than what I'd usually mean -- on platforms I use it (Android), Google Sheets definitely has pinch to zoom (and it's been awhile since I've used Excel but I was pretty sure it did too -- the docs confirm it indeed does: https://support.microsoft.com/en-us/office/excel-for-android...).
I have not but I honestly don't find it to bother me on gsheets whatsoever (I've never thought twice about it until now. Data entry is way way more annoying on gsheets than navigating is).
