cross referenceing data in excel

[Dave O'Connor]

I have two data sets in excel, each with the same unique id. I am trying to
enrich the data from one data set with the other. Therefore if for example I
have name and address details & the unique ID on one sheet AND I have say
annual spend and unique ID on another sheet. I want to combine the data sets
using the unique ID as the identifier and create one whole data set. ie. have
one data set with unique ID, name & Address and spend on one sheet

Can this be done?

VLOOKUP can give you just what you wantSuppose we have a table of pet IDs,
pet names and pet types starting in A1:

100 oscar dog
500 daisey cat
55 rover dog
34 mini goldfish

and another table of pet IDs and pet ages starting in A7:

500 6
100 4
34 1
55 12

To combine the tables in D1 put =VLOOKUP(A1,$A$7:$B$10,2,0) and copy down.

One way using INDEX and MATCH..

Assume in Sheet1, data is in cols A to C, from row2 down
with unique IDs in col C

Name Add ID
Nam1 Ad1 ID1
Nam2 Ad2 ID2
Nam3 Ad3 ID3
Nam4 Ad4 ID4

In Sheet2, data is in cols A and B, from row2 down
with unique IDs in col B

Spend ID
100 ID1
200 ID2
300 ID3
400 ID4

Let's bring over Spend from Sheet2 into col D in Sheet1

In Sheet1
---------
Put in D2:
=IF(ISNA(MATCH(Sheet1!C2,Sheet2!B:B,0)),"",
INDEX(Sheet2!A:A,MATCH(Sheet1!C2,Sheet2!B:B,0)))

Copy D2 down as far as required, and you'd get:

Name Add ID Spend
Nam1 Ad1 ID1 100
Nam2 Ad2 ID2 200
Nam3 Ad3 ID3 300
Nam4 Ad4 ID4 400
etc

Adapt to suit ..

Hi,
If your ID column is the first column in your data sets then you can use a VLOOKUP, if not then use a combination of INDEX and MATCH.
Say your ID #'s are in column A on the main sheet and your ID #'s in column A and annual spend data in column B of sheet 2 then:
=VLOOKUP(A1,Sheet2!A1:B10,2,0)

If your annual spend is in say column A and your ID #'s in column B then:
=INDEX(Sheet2!A1:A10,MATCH(A1,Sheet2!B1:B10,0))


Hope this helps!
