Capstone: clean up an exported contact list
Trim, re-case and slice, all in one pass.
Task:
This came out of an old HR system with stray spaces and shouting capitals. In column C give the name tidied up and properly capitalised, in column D just the five-digit part of the staff code, and in column E how many characters the tidied name has.

What this exercise teachesMay contain the answer
Nesting is the point: TRIM hands its result straight to PROPER without a helper column. The LEN column is the check people skip — if it still counts the padding, the trim never happened, and you will find out much later when a join fails to match.
