We use Google Sheets, as we changed from Office at the beginning of this year, and 10-15 times a day my tab crashes on Chrome from just existing, let alone when trying to do any operations.
It's a mess, and I'd rather build a simple web app to replace it, but don't have the time, approval, or financial resources to make the switch. So instead of letting me improve 100+ peoples daily workflows, we just suffer.
Go spreadsheets!
