Removing duplicate addresses with unique person names

问题

I have duplicate addresses with different names in each row of Excel. I have about 17,000 entries that I need to clean up. Here is an example:

    Name        Address             City                    Zip
-----------------------------------------------------------------
1   Al a Moe    7009 Plainfield     Dearborn Heights MI     48127
2   Al a Adel   7009 Plainfield     Dearborn Heights MI     48127
3   Al a Amy    7009 Plainfield     Dearborn Heights MI     48127
4   Al a Ashly  7009 Plainfield     Dearborn Heights MI     48127

How do I delete the rows with the duplicate addresses, without mixing up the database of names and addresses and only keeping one address per name?

I need a formula that can fix it to only one row with one address and one name

Thanks.

String together the address components in a 'helper column' (Address&City&Zip) then apply Remove Duplicates to that column (only). Apply Remove Duplicates to the Name column only and delete the helper column.
