I have a database of names & addresses. I am sent a revised database
monthly. The headings are the same, however some of the names & addresses may
change.

Is there an easy way of compariing the 2 for duplicates or up-dated
information and saving as a new up-dated sheet?

ie
Current data
Title First Name Surname
Mr Andrew Aalders-Dunthorne
Ms Carolyn Abbott
Dr David Abbott
Cllr James Abbott
Mr Ben Abbotts
Mr Mohammed Abdel-Haq
Mr Mel ab Owain

New data
