SheetMagic Verdict: Gem 💎
It works really well so far. The warning about Sheet access to your account might be slightly worrying (it always happens for me with sheet add-ons), but seems to be 'solved' by using a separate gmail account and then sharing the sheet with your main account. You then don't have to weaken the security of your main account. The templates and examples work fine - just put your prompt into a cell e.g. a12 and then put =ai(a12) into another cell and it's executed. This first step seemed to be missing from the instructions (maybe I missed it or it's obvious to others) but it was a really minor hurdle since it was what I expected to work. Now I'm flying. I'm hoping to find tips on how best to export the content I make. Copy/paste obviously, but maybe there are ways to automate it. Great product already, with a Chrome extension coming soon. I'm hoping that will be additional and not just replace the sheet method. BYOK at all tiers is another big plus - other products take note! It's a keeper.
