I'm trying to find out if there is a way to do this. i have a list of 15k serial numbers. several of them repeat because the value vary. i need to be able to type the serial number into a different sheet and it insert the average value for it in the adjacent cell. the tricky part is i need it to search 'exact stings' ex if i type in da1 it only returns value for that number not x09da123. not sure if this is possible but i have to do this manually over 100 times a day and its very time consuming. and please try to explain simply i'm far from a newbie when it comes to excel but i learn thing as i need them and i'm definitely not an expert lol.
Find Serial Number and input Average Value into Adjacent cell
