Turn today's order log into a prep list
UNIQUE hands back each value once — the fast way to turn a raw log into a prep list.
Task:
You run a food truck. Today's point-of-sale log recorded every order as it came in, and the popular items repeat many times. In E2, use UNIQUE to list every distinct item sold today from B2:B9, so you know what to prep more of tomorrow.
The daily challenge is part of Pro
A new exercise every morning, plus every day that came before it — a back catalogue that grows by one a day, whether or not you were here for it.
