Question

Is it possible to lookup values in excel in the following method:

Table 1

ID    |     Code
-----------------
1     |      I
1     |      J
1     |      K
2     |      I
2     |      J
2     |      L

Table 2

ID    |    I      |    J    |    K    |    L    
----------------------------------------------
1     |   14.40   |  12.33  |  9.21   |  
2     |   13.99   |  11.28  |         |   32.33

The lookup would be to add the column values in table 2 next to the table ‘code’ in table 1. So table 1 would change to:

Table 1

ID    |  Code  |  Amount
-------------------------
1     |   I    |   14.40
1     |   J    |   12.33
1     |   K    |   9.21 
1     |   L    |   
2     |   I    |   13.99
2     |   J    |   11.28
2     |   K    |   
2     |   L    |   32.33

As a reminder, this is a project being run in Microsoft Excel 2003.

Update

I believe I can use a vlookup on the first column and given I know the placement of the code fields, I could go this route but the issue would be I cannot copy and paste this formula across an entire column because the order of which codes may appear can vary (and are not the same from ID to ID).

Answer 1

You can use Index and Match

=INDEX($C$4:$E$6,MATCH(H3,$B$4:$B$6,0),MATCH(I3,$C$3:$E$3,0))

Match finds the position of your ID and code in the Table 2 row and column headers. Index uses those to return the intersection of the row & column.
