Excel functions (by category) | Microsoft Support
In newer versions of Excel, these functions were replaced with new functions that provide improved accuracy and have names that better reflect their usage. You can still use them for compatibility with earlier versions of Excel, but if backward compatibility isn't required, you should start using the new functions instead.

What do you think are the most useful Excel functions most people don’t know about?
If you want to evaluate part of a formula, highlight it and press F9. Very useful when trying to find errors. e.g. if you have the formula: = (A1 - B1) / A1 and you highlight the first part, and press F9 it will temporarily change to: = 1200 / A1 This really comes in handy when you have multi-part formulas and need to workout what clause or function within it isn't working. If you want to know more about functionality that most people don't know about, try looking at Power Query, which is great for doing repetitive data processing. If you just want to take an interest in some little-known formulas, go to the Formulas tab on the ribbon and click through all the formula groups, starting with 'Financial'. You can find some fascinating things in there, especially under Lookup & Reference, although you might find other things appealing. More on reddit.com

My favorite 12 Excel functions that will increase your productivity!
INDEX and MATCH are still good to learn. Even if you have 365 its faster with large sets than XLOOKUP. I’d add RIGHT/LEFT/MID and FIND, ISNUMBER, and SEARCH. I use these frequently to extract specific data from strings. Wildcards are important to learn too in my opinion. Useful in a variety of formula. More on reddit.com
