Excel Tutorial: How To Link Two Excel Sheets Using Vlookup


If you have ever worked with large amounts of data in Excel, you know how important it is to efficiently manage and analyze that data. One essential function that can help you achieve this is the vlookup function. This powerful tool allows you to search for a value in one column of data and return a corresponding value from another column. In this tutorial, we will explore the vlookup function and learn how to use it to link two Excel sheets. This skill is invaluable for anyone who wants to streamline their data management and make complex analyses simpler and more accurate.

Key Takeaways

  • The vlookup function in Excel is essential for efficiently managing and analyzing large amounts of data.
  • Linking two Excel sheets using vlookup can streamline data management and make complex analyses simpler and more accurate.
  • Understanding the definition, syntax, and parameters of vlookup is crucial for using it effectively.
  • Setting up and organizing the data in both sheets is important for accurate linking using vlookup.
  • Best practices for linked sheets include documenting the vlookup setup for future reference and regularly reviewing and updating the linked data.

Understanding VLOOKUP

When working with Excel, the VLOOKUP function is a powerful tool that allows you to link two excel sheets and retrieve data from one sheet to another. This function is commonly used for data analysis and report generation.

Definition of VLOOKUP

The VLOOKUP function stands for "vertical lookup" and is used to search for a value in the first column of a table and return a value in the same row from another column.

Syntax and parameters of VLOOKUP function

The syntax of the VLOOKUP function is:

  • Lookup_value: The value to search for.
  • Table_array: The range of cells containing the data to be searched.
  • Col_index_num: The column number in the table from which to retrieve the value.
  • Range_lookup: Optional. A logical value that specifies whether you want VLOOKUP to find an exact match or an approximate match.

Examples of VLOOKUP in action

Here are some examples of how VLOOKUP can be used:

  • Using VLOOKUP to retrieve a student's grade from a separate table of student names and grades.
  • Linking two excel sheets by using VLOOKUP to pull in data from one sheet into another based on a common identifier.
  • Using VLOOKUP to find and extract specific data from a large dataset for analysis or reporting purposes.

Setting up the Two Excel Sheets

When linking two excel sheets using vlookup, it's important to set up the sheets in a way that allows for seamless data retrieval. This involves identifying key columns for linking, organizing the data in both sheets, and ensuring data consistency and accuracy.

Identifying the key columns for linking
  • Understand the relationship:

    Before setting up the sheets, it's crucial to understand the relationship between the two datasets. Identify the common data points that will serve as the basis for linking the sheets.
  • Choose the key columns:

    Once the relationship is clear, choose the key columns from each sheet that will be used for the vlookup function. These columns should contain unique identifiers or data points that are consistent across both sheets.

Organizing the data in both sheets
  • Arrange the data:

    Ensure that the data in both sheets is organized in a clear and structured manner. This may involve sorting the data based on the key columns identified for linking.
  • Create a table:

    Consider converting the data in both sheets into tables. This can make it easier to manage and reference the data when setting up the vlookup function.

Ensuring data consistency and accuracy
  • Check for errors:

    Before proceeding with the vlookup, thoroughly review the data in both sheets for any errors, inconsistencies, or missing values. This step is crucial for accurate linking and data retrieval.
  • Standardize formats:

    Ensure that the data formats in the key columns are consistent across both sheets. This may involve standardizing date formats, number formats, or any other relevant data types.

Using VLOOKUP to Link the Sheets

When working with multiple Excel sheets, it's often necessary to link the data between them. One way to do this is by using the VLOOKUP function, which allows you to search for a value in one sheet and return a corresponding value from another sheet. Here's how to use VLOOKUP to link two Excel sheets:

Writing the VLOOKUP formula

The first step in using VLOOKUP to link two Excel sheets is to write the VLOOKUP formula. This formula is used to look up a value in a table and return a corresponding value from a different column. The basic syntax for the VLOOKUP formula is =VLOOKUP(lookup_value, table_array, col_index_num, [range_lookup]).

Specifying the lookup value and table array

Once you have written the VLOOKUP formula, the next step is to specify the lookup value and the table array. The lookup value is the value you want to search for in the first sheet, while the table array is the range of cells in the second sheet where you want to search for the lookup value.

Handling errors and troubleshooting

When using VLOOKUP to link two Excel sheets, it's important to be aware of potential errors and how to troubleshoot them. Common errors include #N/A, which means the lookup value was not found, and #REF, which means the table array is not valid. To handle these errors, you can use the IFERROR function to display a custom message or value when an error occurs.

Enhancing the Linked Data

Once you have successfully linked two excel sheets using VLOOKUP, there are several ways to enhance the linked data to make it more functional and user-friendly.

a. Using VLOOKUP with other functions

One way to enhance the linked data is by combining VLOOKUP with other functions in Excel. For example, you can use VLOOKUP in conjunction with IF, AND, or OR functions to create more complex and dynamic data relationships. This can be particularly useful when dealing with large datasets or when you need to perform more advanced calculations based on the linked data.

b. Sorting and filtering the linked data

Another way to enhance the linked data is by utilizing the sorting and filtering capabilities in Excel. Once the two sheets are linked, you can easily sort and filter the data based on specific criteria. This can help you analyze the linked data more effectively and extract valuable insights from it.

c. Updating the link as new data is added

As new data is added to either of the linked sheets, it is important to update the link to ensure that the data remains accurate and up-to-date. You can do this by simply refreshing the VLOOKUP function or by using dynamic named ranges to automatically expand the linked range as new data is added. This will help maintain the integrity of the linked data and prevent any discrepancies or errors.

Best Practices for Linked Sheets

When linking two excel sheets using VLOOKUP, it is important to follow some best practices to ensure the data remains accurate and easily manageable.

Keeping sheet names and data ranges in mind

  • Use clear and descriptive sheet names:

    Having clear and descriptive sheet names will make it easier to identify and reference the linked sheets in the VLOOKUP formula.
  • Define specific data ranges:

    Instead of linking entire columns, define specific data ranges to ensure the VLOOKUP formula is efficient and accurate.

Documenting the VLOOKUP setup for future reference

  • Create a clear and organized documentation:

    Document the VLOOKUP setup, including the sheet names, data ranges, and VLOOKUP formulas used, for future reference and troubleshooting.
  • Include any additional notes or considerations:

    Add any additional notes or considerations for the VLOOKUP setup, such as any specific formatting requirements or data validation rules.

Regularly reviewing and updating the linked data

  • Schedule regular reviews of the linked data:

    Set a schedule to review and verify the linked data to ensure it remains accurate and up-to-date.
  • Update the VLOOKUP formulas as needed:

    Update the VLOOKUP formulas as the data ranges or sheet names change to avoid any errors or inaccuracies in the linked data.


Linking two Excel sheets using VLOOKUP offers numerous benefits, including streamlining data management and reducing the likelihood of errors. By establishing a connection between the two sheets, you can easily pull in data from one sheet to another, making your analysis and reporting more efficient and accurate.

We encourage you to practice and explore other Excel functions to further enhance your spreadsheet skills. There are countless functions and features in Excel that can help you become a more efficient and effective data analyst or professional.
