WHO ARE YOU? No, It is Chuck, you can delete my old profile because I changed my email address. I was reading the thread and thought it was about teaching coding. I guess I misunderstood. Because I use Google Sheets which is basically the same as Excel. Google Sheets uses Apps Script in order to code functions. Apps Script is Java based which you are able to use Python to be added. In saying that, I know you use AI and an old style cold from the 90's in previous conversations we have had. So I have decided to learn Java via Youtube. So, perhaps as I go, I will touch base in terms of strategies as you say.
