Excel Copy Column Value Based On Another Column Value Lookup

Problem:
One Excel sheet named “Account Info” contains accountnumber and account name. The other sheet named “Order Info” contains order mapping between orderid and accountnumber. Now we need to add another column to the second sheet to show the matching customer name from the first sheet. The two sheets are shown below.

Solution:
The build in functions IFERROR and VLOOKUP can be used together for this job. You can simply enter

=IFERROR(VLOOKUP(B2, ‘Account Info’!A:B, 2, 0),”N/A”)

as the formula of the cell C2 on the sheet “Order Info”. Then drag it all the way down to cover all your rows.

Explanation:
VLOOKUP can be used to look up a specified value (its first parameter in this example) from the specified table data(the 2nd parameter) and return the matched data(the third parameter). 0 here indicates exact match. If no match can be found, then IFERROR will set the value to “N/A”. See Microsoft Support for more details.
