I have two sheets, one is a huge table of item ID's with a corresponding code column next to them. However over time this has not been properly filled in. I have assembled a complete list of item ID's and corresponding codes in another sheet.
I want Excel to fill in the blanks using the ID column as a key.
What's the easiest way to get Excel to look for the ID in the main sheet, and paste in the corresponding code from the other sheet?
