Comparing two columns in Excel can be a daunting task, especially when dealing with large datasets. However, with the help of the VLOOKUP function, you can easily compare two columns and retrieve data from another column based on a match. In this article, we will explore the VLOOKUP function and its application in comparing two columns in Excel.
Understanding the VLOOKUP Function
The VLOOKUP function is a powerful tool in Excel that allows you to search for a value in a table and return a corresponding value from another column. The function takes four arguments: the value to search for, the range of cells to search in, the column number to return a value from, and an optional range lookup argument.
How to Use VLOOKUP to Compare Two Columns
To compare two columns using VLOOKUP, follow these steps:
- Identify the two columns you want to compare. For example, let's say you have a table with two columns, "Employee ID" and "Department".
- Create a new column next to the table to display the results of the comparison.
- In the new column, enter the VLOOKUP function, using the following syntax:
VLOOKUP(lookup value, table array, col index num, [range lookup]). - In the
lookup valueargument, enter the value you want to search for in the first column (e.g., "Employee ID"). - In the
table arrayargument, select the range of cells that contains the data you want to search (e.g., the entire table). - In the
col index numargument, enter the column number that contains the data you want to return (e.g., 2 for the "Department" column). - Set the
[range lookup]argument to FALSE to perform an exact match.
Example:
=VLOOKUP(A2, B:C, 2, FALSE)
This formula searches for the value in cell A2 in the first column of the range B:C and returns the corresponding value in the second column.

col index numargument. - Range lookup: Set the
[range lookup]argument to FALSE to perform an exact match. - Lookup value: Ensure that the
lookup valueargument is correct and matches the format of the data in the table.
