I have a drop down list of about five hundred items that my four vendors can select from. I'm trying to track trends of frequent selections, such as the top five things + how many times it's been selected within 30 days + who has selected what.
I've used =COUNTIFS(Item:Item, "item name", Date:Date, >=TODAY(-30)) in the sheet summary to count specific things on a small scale, but I know there's a solution for large scale data collection that I've overlooked/can't remember.
Could someone point me in the right direction? Thank you!
