This is my data:
File1 Name School Age Weight Jack St John 15 Jack St Mary 14 Jack St Michael 12 Mary St John 16 Mary St Mary 12 Mary St Michael 15
Raw data
Name School Weight Jack St John 80 Jack St Mary 75 Jack St Michael 95 Mary St John 75 Mary St Mary 65 Mary St Michael 80
I want to fetch Weight values referring Raw data.
I tried with MATCH and INDEX, however I kept on getting #VALUE!.
Any ideas what to use to fetch these Weight values?
回答1:
The conventional solution is to use a helper column to make the values unique. So for example in your Raw data insert a column C with =A1&"|"&B1 copied down to suit, then in File 1, D2:
=VLOOKUP(A2&"|"&B2,'Raw data'!C:D,2,0)
copied down to suit.

Here's pnuts answer laid out explicitly.
Raw data
Name School Weight Helper
Jack St John 80 Jack|St John
Jack St Mary 75 Jack|St Mary
Jack St Michael 95 Jack|St Michael
Mary St John 75 Mary|St John
Mary St Mary 65 Mary|St Mary
Mary St Michael 80 Mary|St Michael
The formula in the helper column is:
=A2&"|"&B2 just as pnuts suggested
File1
Name School Age Weight
Jack St John 15 80
Jack St Mary 14 75
Jack St Michael 12 95
Mary St John 16 75
Mary St Mary 12 65
Mary St Michael 15 80
The formula in the Weight column is:
=INDEX('[Raw data.xlsx]Sheet1'!$C$2:$C$7,MATCH(A2&"|"&B2,'[Raw
data.xlsx]Sheet1'!$D$2:$D$7,0))
It worked first time out so I don't know why you're getting #Value.
