New from Albuquerque NM

Hey, I use to be pretty good with a spreadsheet way back 98, things have changed a lot in Excel and it’s time to relearn what I use to know. Extracting data has been made more simple but apparently requires a better understanding of how the tools work. I have never used VBA but I think it is time to start learning. I am retired so all this is going back to school for me. Suggestions on what to read or watch are always welcome. I like learning and even though I will never use it professionally; I like knowing the HOW. I used to use this forum all the time in 2006, I was working in Iraq as a truck driver but pointed out to my employer (who had to report data to the government) their data was way off. Filled in for a manager on leave and was looking at his spreadsheets and found errors that lead to 5 million gallons of water delivered but not showing up in the spreadsheets lol. So after that people started asking me to look at things and build better spreadsheets. So I am back just trying to learn because I thought it was kind of fun thing to do.
Thank You,
Ken
