You and I must be same generation. I started with Lotus as well (and, by the way, I suspect Microsoft would not look kindly on your saying that Excel "was then called Lotus 1-2-3"). It was Lotus, certainly, that took the fledgling PC industry and made it corporate-cool by giving us all the ability to do our own financial analyses. Over the years I worked at home with Quattro, another spreadsheet contender, put out by the Borland company; Lotus at work, but ultimately Excel in both places. I retired twenty years ago next month....and continue to have fun with Excel.
As to your question, there is a volume entitled "Excel for Dummies" (there's a "____________ for Dummies" on just about every software package, I think, and they're actually pretty good. I've never used the Excel version, but I have used them for other packages). On Excel, I generally now just go to various websites (this one included). Exceljet is one that I find particularly clear and useful. Since you did use it a lot back in the early days, you might find some of the YouTube videos--on just about every feature under the sun--to be to your liking. Personally, I miss the software manuals! Used to read and re-read them, always discovering something new--"Oh, that's a way to do X more directly!"--I'd realize. There are new functions coming out regularly......and it's fun learning them. One of the reasons I like to answer questions here is that it is a way for me to learn.
