What is the VLOOKUP Function?

Defination

The VLOOKUP function in Excel is a built-in function used to search for a value in the first column of a table array and return a corresponding value in the same row from a specified column.

Purpose

The purpose of using the VLOOKUP function in Excel is to search for a specific value in a table, retrieve corresponding information from that table, and use it for various data analysis, reporting, and decision-making tasks.

Syntex for Excel VLOOKUP Function:

Syntex

The syntax for the VLOOKUP function in Excel is as follows:

= VLOOKUP(lookup_value, table_array, col_index_num, [range_lookup])

lookup_value: The value to search for in the first column of the table array.
table_array: The range of cells that contains the data. It must include the column from which to retrieve the return value.
col_index_num: The column number in the table array from which to retrieve the return value.
[range_lookup]: Optional. It specifies whether to perform an approximate or exact match. Enter TRUE for approximate match or FALSE for exact match. If omitted, it defaults to TRUE or approximate match.

Return Value

The return value of the VLOOKUP function is the value retrieved from the specified column of the table array based on the lookup value provided.

How to Use:

Here’s how to use the VLOOKUP function with the syntax:

  1. Select a Cell: Choose the cell where you want the result of the VLOOKUP function to appear.
  2. Enter the Function: Type =VLOOKUP( into the selected cell.
  3. Input Parameters: Provide the required parameters:
    lookup_value: Enter the value you want to search for.
    table_array: Select the range of cells that contains the data, including the column from which you want to retrieve the return value.
    col_index_num: Specify the column number in the table array from which you want to retrieve the return value.
    [range_lookup]: Optionally, enter TRUE for an approximate match or FALSE for an exact match. If omitted, it defaults to TRUE.
  4. Close the Function: Close the function by typing ) and then press Enter.

Example:


=VLOOKUP(A2, $B$2:$D$10, 2, FALSE)


This formula searches for the value in cell A2 within the range B2:D10, retrieves the corresponding value from the second column of that range, and ensures an exact match.

Examples with Description

Example 01: Retrieving Sales Data:

=VLOOKUP(“Product A”, A2:B10, 2, FALSE)

This formula looks for “Product A” in the range A2:B10, and returns the corresponding sales data from the second column (column B). It ensures an exact match.

Example 02: Finding Employee Salary:

=VLOOKUP(“John”, E2:G10, 3, FALSE)

This formula searches for “John” in the range E2:G10, and retrieves his salary from the third column (column G). It ensures an exact match.

Example 03: Identifying Customer Details:

=VLOOKUP(101, H2:J10, 2, FALSE)

This formula looks for the customer ID “101” in the range H2:J10, and returns the corresponding customer name from the second column (column I). It ensures an exact match.

Common Mistakes

Common Error

1. #N/A Error: Explanation: This error occurs when the VLOOKUP function cannot find the specified value in the first column of the table array.

2. #REF! Error: Explanation: This error occurs if the referenced range for the table array is invalid or deleted.

3. #VALUE! Error: Explanation: This error occurs if the supplied parameters are incorrect or if there are inconsistencies in the data types.

How to solve

1. #N/A Error:

  • Solution: Verify that the lookup value exists in the first column of the table array. Check for spelling mistakes or formatting inconsistencies.

2. #REF! Error:

  • Solution: Check if the range for the table array is correctly specified and valid. Ensure that no cells within the referenced range are deleted or modified.

3. #VALUE! Error:

  • Solution: Double-check the syntax of the VLOOKUP function and ensure that all parameters are entered correctly. Make sure that the data types of the lookup value and the first column of the table array match.

How to Avoid

  • Double-check the data: Ensure that the lookup value exists in the first column of the table array.
  • Use absolute cell references: Use absolute cell references (e.g., $A$2:$B$10) for the table array to prevent accidental changes.
  • Validate data types: Make sure that the data types of the lookup value and the first column of the table array match to avoid #VALUE! errors.
  • Error handling: Implement error-handling techniques, such as using IFERROR function, to handle potential errors gracefully and improve the reliability of your formulas.
  • Data consistency: Keep your data consistent and regularly validate the integrity of your datasets to minimize errors during lookup operations.

Advance tips and Tricks:

Here are some advanced tips and tricks for effectively using this function in Excel:

Performing a Two-Way Lookup with VLOOKUP and CHOOSE:

Tip: Utilize VLOOKUP along with CHOOSE to perform a two-way lookup, enabling you to search for a value in both rows and columns.

=VLOOKUP(lookup_value, CHOOSE({1,2}, row_lookup_range, column_lookup_range), 2, FALSE)

By nesting CHOOSE inside VLOOKUP, you can create a versatile formula that searches for a value across both rows and columns in a table, returning the intersecting data point.

Using VLOOKUP with Wildcards for Partial Matches:

Tip: Employ wildcard characters (* or ?) with VLOOKUP to perform partial matches, allowing you to find values based on patterns rather than exact matches.

=VLOOKUP(““&lookup_value&”“, table_array, col_index_num, FALSE)

By appending wildcard characters to the lookup value within the VLOOKUP formula, you can retrieve data that partially matches the specified criteria, providing more flexible search capabilities.

Implementing VLOOKUP with IFERROR for Error Handling:

Tip: Combine VLOOKUP with IFERROR to handle errors gracefully and improve the robustness of your formulas.

=IFERROR(VLOOKUP(lookup_value, table_array, col_index_num, FALSE), “Not Found”)

By wrapping VLOOKUP within IFERROR, you can display a custom message (e.g., “Not Found”) instead of error values like #N/A, enhancing the readability and usability of your spreadsheet.

Using VLOOKUP with Data Validation for Interactive Lookup:

Tip: Integrate VLOOKUP with Data Validation to create interactive lookup functionality, allowing users to select values from predefined lists.

=VLOOKUP(data_validation_cell, table_array, col_index_num, FALSE)

By linking the VLOOKUP formula to a cell with data validation, you enable users to choose lookup values from a dropdown list, enhancing ease of use and reducing input errors in your Excel workbooks.y
