That depends. Is the spreadsheet doing what it’s intended for, or one of the hundreds of things it can do but really shouldn’t?

I’ve made my fair share of spreadsheets, including time tracking, vehicle scheduling, email automations, map integrations, god forgive me even ‘databases’ - all of that because no one was willing to pay for a proper solution.

So I’m not saying spreadsheets can’t or shouldn’t ever be used for those things, but a dedicated solution for a problem may indeed be a good reason to change things.
