Intro
Learn to lookup 2 columns in Excel using VLOOKUP, INDEX-MATCH, and other functions for efficient data retrieval and management, including merging tables and handling multiple criteria searches.
Looking up data in Excel can be a daunting task, especially when dealing with large datasets. However, with the right tools and techniques, it can be made easier and more efficient. One of the most common tasks in Excel is looking up data in two columns. This can be useful in a variety of situations, such as finding a specific value in a table or retrieving data from a database.
In this article, we will explore the different ways to look up data in two columns in Excel. We will cover the various formulas and functions that can be used, including VLOOKUP, INDEX/MATCH, and LOOKUP. We will also discuss the benefits and limitations of each method and provide examples of how to use them.
Understanding the Problem
Before we dive into the solutions, let's take a closer look at the problem. Suppose we have a table with two columns, "Name" and "Age". We want to find the age of a specific person, say "John". We can use a lookup function to search for "John" in the "Name" column and return the corresponding value in the "Age" column.
VLOOKUP Function
The VLOOKUP function is one of the most commonly used lookup functions in Excel. It searches for a value in the first column of a table and returns a value in the same row from another column. The syntax for VLOOKUP is:
VLOOKUP(lookup_value, table_array, col_index_num, [range_lookup])
- lookup_value: the value to search for
- table_array: the range of cells to search in
- col_index_num: the column number to return a value from
- [range_lookup]: optional, specifies whether to search for an exact match or an approximate match
For example, if we want to find the age of "John" using VLOOKUP, we can use the following formula:
=VLOOKUP("John", A:B, 2, FALSE)
This formula searches for "John" in the first column of the range A:B and returns the value in the second column.
Benefits and Limitations of VLOOKUP
The VLOOKUP function is easy to use and provides a simple solution for looking up data in two columns. However, it has some limitations. For example, it can only search for a value in the first column of a table, and it can be slow for large datasets.INDEX/MATCH Function
The INDEX/MATCH function is another powerful lookup function in Excel. It uses the INDEX function to return a value from a range of cells and the MATCH function to search for a value in a range of cells. The syntax for INDEX/MATCH is:
INDEX(range, MATCH(lookup_value, range, [match_type]))
- range: the range of cells to return a value from
- lookup_value: the value to search for
- range: the range of cells to search in
- [match_type]: optional, specifies whether to search for an exact match or an approximate match
For example, if we want to find the age of "John" using INDEX/MATCH, we can use the following formula:
=INDEX(B:B, MATCH("John", A:A, 0))
This formula searches for "John" in the range A:A and returns the value in the range B:B.
Benefits and Limitations of INDEX/MATCH
The INDEX/MATCH function is more flexible than VLOOKUP and can search for a value in any column of a table. It is also faster and more efficient for large datasets. However, it can be more complex to use and requires a good understanding of the INDEX and MATCH functions.LOOKUP Function
The LOOKUP function is another lookup function in Excel that can be used to search for a value in a range of cells. The syntax for LOOKUP is:
LOOKUP(lookup_value, table_array)
- lookup_value: the value to search for
- table_array: the range of cells to search in
For example, if we want to find the age of "John" using LOOKUP, we can use the following formula:
=LOOKUP("John", A:B)
This formula searches for "John" in the range A:B and returns the value in the same row.
Benefits and Limitations of LOOKUP
The LOOKUP function is easy to use and provides a simple solution for looking up data in two columns. However, it has some limitations. For example, it can only search for a value in the first column of a table, and it can be slow for large datasets.Gallery of Lookup Functions

Frequently Asked Questions
What is the difference between VLOOKUP and INDEX/MATCH?
+VLOOKUP searches for a value in the first column of a table and returns a value in the same row from another column. INDEX/MATCH searches for a value in any column of a table and returns a value from another column.
How do I use the LOOKUP function in Excel?
+The LOOKUP function searches for a value in a range of cells and returns a value from the same row. The syntax for LOOKUP is: LOOKUP(lookup_value, table_array).
What are the benefits of using INDEX/MATCH over VLOOKUP?
+INDEX/MATCH is more flexible than VLOOKUP and can search for a value in any column of a table. It is also faster and more efficient for large datasets.
In conclusion, looking up data in two columns in Excel can be a complex task, but with the right tools and techniques, it can be made easier and more efficient. The VLOOKUP, INDEX/MATCH, and LOOKUP functions are all powerful lookup functions that can be used to search for a value in a range of cells and return a value from another column.
