What is VLOOKUP?

How to get started

To start using VLOOKUP:

  1. Start by clicking the cell where you want to see the results and enter an equal (=) sign, followed by VLOOKUP and parentheses.
  2. Inside the parentheses, you'll need to enter a set of arguments. An argument is just a piece of data that the function needs to run.

  3. Enter the value you know, such as a product name, as the first argument.
    VLOOKUP > first argument
  4. Type a comma, then enter the range of cells containing the data you want to search. For example, the block of data that contains your product names and prices.

  5. Type another comma and then enter the column index number of the data you want to see. For instance, if you want to see the price of a product, and the price data is in the third column from the left, enter the number 3.

  6. Add another comma and enter FALSE for an exact match between the data you know and the data you want to see. If you enter TRUE, you'll get an approximate match.
  7. Press Enter to see the results.
  8. If you don't enter a value in the left-hand column, you'll get an error message.

  9. Once you enter a value in the left-hand column, you'll get the corresponding value in the third column to the right.

VLOOKUP in financial modeling and financial analysis

VLOOKUP is useful in everyday tasks and finance-related activities such as financial modeling and analysis. Financial models help companies plan their finances and make projections for the future. 

VLOOKUP formulas are used in financial modeling to make these models more dynamic and include various scenarios.

For example:

A sales manager may want to analyze Cost per Conversion to determine which conversions are selling best. By using VLOOKUP, they can easily match the Conversions with the Cost per Conversion and extract data.

This information can then be used to make informed decisions on how to allocate resources, adjust pricing strategies, or launch new products in specific regions.

VLOOKUP can also be used to identify top-performing salespeople by matching their names with sales data and extracting key metrics such as total sales, number of deals closed, and average deal size.

Overall, VLOOKUP can be a powerful tool for sales analysis, providing valuable insights into customer behavior and sales performance that can help drive business growth.

Things to remember about the VLOOKUP Function

The VLOOKUP function is a useful tool in Excel that helps you find information in a table or dataset. Here are some things to remember when using this function:

  • If you don't specify whether you want an exact match, VLOOKUP will allow for non-exact matches but will use exact matches if they exist.
  • VLOOKUP only looks to the right of the first column in the table, so it's limited in that sense.
  • If the column you're looking at has duplicate values, VLOOKUP will only match the first one.
  • The function doesn't care about capitalization or lowercase letters, so "apple" and "APPLE" are treated the same.
  • Inserting or deleting a column in the table may break the VLOOKUP formula because the column index values don't update automatically.
  • You can use wildcards like * and ? in the lookup value to help find matches.
  • If numbers are entered as text in the table, you may get an error if the lookup value isn't in text form.
  • You might see different error messages when using VLOOKUP, including #N/A!, #REF!, and #VALUE!.

Remembering these tips can help you use the VLOOKUP function more effectively and avoid common mistakes.

What is the most common use for VLOOKUP?

The VLOOKUP function in Excel is often used when you want to find a specific piece of information in a big table or list of data. 

This function is great when you need to search for a particular item and then get some information about that item from another column in the same row.


Suppose we want to know how much the customer paid for the product they bought. We could use the VLOOKUP function to find the Price Per Unit for each order.


How to troubleshoot errors in VLOOKUP function?

Sometimes when using the VLOOKUP function, you might encounter errors that prevent it from returning the desired result. If you are confident that the data you are searching for is present in your spreadsheet, then the issue might be due to hidden spaces or non-printing characters in the referenced cells.

Therefore, it is important to verify that your cells do not have any of these issues and that they follow the correct data type.

To troubleshoot VLOOKUP errors, you can:

  1. Check the format of the lookup value to ensure that it matches the format of the value in the first column of the lookup table. 
  2. Double-check the range_lookup argument to ensure that it is either TRUE or FALSE, and not a different value. 
  3. Use the IFERROR function to catch errors and return a custom message instead of an error code. 

By taking these steps, you can increase the accuracy of your VLOOKUP function and ensure that you are getting the desired results.

When should you not use VLOOKUP?

Although VLOOKUP is a very useful function, there are certain situations when it should not be used. 

For example:

If you plan to add or delete columns in your data, VLOOKUP may return incorrect results as the column number reference would now be incorrect. To make the column number dynamic, additional formulas, and functions must be used, which can become complicated. 

In this case, using the INDEX/MATCH combination function may be better.

The INDEX/MATCH function combination can handle dynamic column ranges without the need to modify formulas every time new data is added or removed. It is also generally faster than VLOOKUP when searching large datasets.

 Therefore, it's essential to understand the limitations of VLOOKUP and know when to use INDEX/MATCH combination or other Excel functions, depending on the specific needs of the task at hand.

Final Thoughts

In conclusion, the VLOOKUP function is a powerful tool in Excel that allows users to quickly search for and retrieve data from a table. 

Users can streamline their work by following the step-by-step process for using the VLOOKUP function and save time and effort in their data processing tasks. 

With a basic understanding of the VLOOKUP function and its capabilities, even beginners can make the most of Excel's powerful data management tools.
