Stuck on combining two lists with different column headers

[MrB1onde]

Hi All,

I have searched far and wide for a solution to my issue, but have yet to come upon one. Here's my situation. I have two lists, each containing ~1,500 items. The column headers are as follows:

List #1:

Column A: Usernames (ie Smith)

Column B: Locations (ie Dallas)

List #2:

Column A: Usernames

Column B: Site hits (ie 38)

From these two lists, I want to extract the duplicate entries(these are the entries in which I am interested) based on the Username field. So basically I want to create a single list like this:

Column A: Usernames (all Usernames common to both lists)

Column B:: The location associated with each particular Username

Column C: The number of site hits associated with each particular Usernames


I have found plenty of references to extracting duplicate entries from two lists, but none where the lists had different column headers. Any help would be greatly appreciated. Thanks in advance!

You could try using the COUNTIF function for each entry in the two lists to see which occur in the other list (i.e. having a count of 1). These could then the sorted to get the common entries into a block. You could then use a VLOOKUP function to bring together the two sets of data. Alternatively, if you have absolutely no duplication within each, you could get away with sorting each list's common entries by username and then just line up the other two columns.
