Merge two excels - Using VLOOKUP to merge 2 Sheets

I have two excel sheets with common column called UPN. One sheet has 650 rows and the other has 600.  Sheet2 (600) only has two columns Column A - UPN and Column B - Last Logon Date. Sheet 1 has 10 columns with various headings. I want to insert column B from Sheet 2 into Sheet 1 corresponding to matching UPN.  I know VLOOKUP is my friend here, but still confused as to how to do this. Any simple explanations to assist me ?

Hi,

Paste this into row 2  of whichever column in Sheet1 you want the Logon information to appear, and copy down 650 rows:
=IFERROR(VLOOKUP(A2,Sheet2!A:B,2,0),"")
It assumes the UPN reference in sheet1 is in Col A, and starting from row 2.
Where there is no match it leaves the cell blank ("").
