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

One way to try ..

Assuming:

Current data is in Sheet1, cols A to C,
data from row2 down to row100

New data is in Sheet2, cols A to C, data from row2 down

In Sheet2
-----------
Using an empty col to the right, say col K?

Put in K2, and array-enter (Press CTRL+SHIFT+ENTER):

=IF(ISNA(MATCH(TRIM(B2)&"_"&TRIM(C2),TRIM(Sheet1!$ B$2:$B$100)&"_"&TRIM(Sheet
1!$C$2:$C$100),0)),ROW(),"")

Copy K2 down as many rows as there is new data in cols A to C

In a new Sheet3
---------------
Put in A1:

=IF(ISERROR(SMALL(Sheet2!$K:$K,ROWS($A$1:A1))),"", INDEX(Sheet2!A:A,MATCH(SMA
LL(Sheet2!$K:$K,ROWS($A$1:A1)),Sheet2!$K:$K,0)))

(Normal ENTER)

Copy A1 across to C1
(or across as many cols as you have actual data to compare)
Fill down by as many rows as was done in Sheet2's col K

Sheet3 will return (if any) all the rows of new data in Sheet2 which does
not match with the current data in Sheet1 at the top, bunched together. The
matching is done using a concat of the First Name and Surname in cols B & C.

We could then select the row(s) returned in Sheet3 and do a copy paste
special as values (and format) over in Sheet1 just below the last row of
data as updates to Sheet1

Adapt to suit ..
