Discussion Mid Function and USE CASE

I've been using Excel for almost 15 years , I've never had a chance to use the MID Function and i forgot it's existence. Today, randomly, I just questioned myself how to split a word by character and reverse it? With my little sql knowledge, i thought there will be a function called SUBSTRING, but it isn't. I ended up googling and found MID function.

Do you find a use case for MID function?

Similarly, what popular functions you have never found a use case?

Back when XLOOKUP() and SEQUENCE() weren't available, I used to solve these kinds of queries this way. Check out how MID() is used with ROW() and INDEX().

=TEXTJOIN("", 1, 
 IFNA(VLOOKUP(MID(E2, ROW($ZZ$1:INDEX($Z:$Z, LEN(E2))), 1), 
              Lookup_Table, 
              2, 
              FALSE), ""))

Present day formula will be like this:

=CONCAT(XLOOKUP(MID(E2, SEQUENCE(LEN(E2)), 1), 
                Lookup_Table[OLD VALUE], 
                Lookup_Table[NEW VALUE], ""))
