Comment Clone Excel, then call me (Score 1) 57

I will finally be impressed with AI-coding; and I will finally be able to leave Microsoft entirely, because the giant mountain of tools that is excel is my one reason I just can't leave; it's too useful.
Oh, clone ODBC while you're at it. Database hits are what Libre Calc particularly sucks at, and for me, database-front-ending and reporting was it's finest feature.
