I have two sheets in my workbook. one is for unique clients, and the other is a combined table with clients and other details.

Say in Sheet A:

ID  |  Name  |  Addr
1   |  Peter |  10a...
2   |  Aaron |  18...
.   |    .   |   .
.   |    .   |   .

In Sheet B:

ID  |  Name  |  Addr
    |  Peter |  10a...
    |  Peter |  10a...
    |  Aaron |  18...
    |  Aaron |  18...

I want to set the ID in sheet B according to the client details. Say, if the content of column “Name” and “Addr” in sheet B equals to the content in “Name” and “Addr” in sheet A, then put the value of “ID” sheet A into sheet B.

So, sheet B should be like this:

ID  |  Name  |  Addr
1   |  Peter |  10a...
1   |  Peter |  10a...
2   |  Aaron |  18...
2   |  Aaron |  18...

How can I do this?

    Use VLOOKUP with Concatenate:

    In Sheet 1, create a unique Concatenated Key for each row by concatenating Name and Address. & is the concatenation operator. Formula: =B2&C2

    Now in Sheet 2, use VLOOKUP using the Concatenated Key:

      = VLOOKUP(B2&C2, Sheet1!$A$2$:$D$500,2,FALSE)

    Some important points here:

    • you’re looking up the matching key (B2&C2)
    • you’re requiring an EXACT match (FALSE),
    • and you’ll pick up ID (column 2).
    • Don’t forget to ANCHOR the reference table (use the $). In the above example, I’ve assumed 500 unique clients in Sheet 1. Fill in as desired.

    Sheet 1:

    Sheet 2:
