Are you tired of scrolling through endless rows of data to find duplicates in your Excel spreadsheet? Don’t worry, VLOOKUP has got your back! With just a few clicks, you can easily spot those pesky duplicates and clean up your data in no time. Let’s dive into how you can use VLOOKUP to make your data squeaky clean.
Step by Step Tutorial: Finding Duplicate Values in Excel Using VLOOKUP
Before we get into the nitty-gritty, let’s understand what we’re aiming for. By following these steps, you’ll be able to identify duplicate values in your data set. VLOOKUP will be your guiding light, leading you to a cleaner, more organized spreadsheet.
Step 1: Set up your data
Start by organizing your data in a table format with headers.
Organizing your data is key. Make sure each column has a clear header to avoid confusion. A tidy table will make the process smoother.
Step 2: Create a new column for VLOOKUP results
Label a new column where you’ll place the VLOOKUP results, typically next to the column you’re checking for duplicates.
This new column will serve as the destination for the VLOOKUP results. Think of it as a detective’s notepad where clues (in this case, duplicates) are recorded.
Step 3: Enter the VLOOKUP formula
In the new column, type in the VLOOKUP formula, referencing the cell you want to check for duplicates.
Getting the formula right is crucial. If you’re not too familiar with VLOOKUP, it’s a good idea to have a reference guide on hand.
Step 4: Drag the formula down
Click and drag the formula down the new column to apply it to all the cells you want to check.
Dragging the formula down ensures that VLOOKUP is on the lookout for duplicates in all the cells you’ve specified.
Step 5: Sort or filter your data
Once you’ve applied VLOOKUP, sort or filter your data to group the duplicate values together.
Sorting or filtering will bring those duplicates out of hiding, making it easier for you to take action.
After completing these steps, you’ll have a list of duplicate values clearly marked in your spreadsheet. This will help you take the necessary steps to clean your data, whether that means removing duplicates or consolidating information.
Tips for Finding Duplicate Values in Excel Using VLOOKUP
- Make sure your reference column in VLOOKUP is the first column in the range you select.
- Lock the range in your VLOOKUP formula by using absolute references (e.g., $A$1:$B$10).
- Use the IFERROR function with VLOOKUP to avoid #N/A errors if no duplicate is found.
- If you have a large dataset, consider breaking it down into smaller sections for quicker VLOOKUP processing.
- Regularly save your workbook to prevent data loss while cleaning up duplicates.
Frequently Asked Questions
Can VLOOKUP find duplicates in two different sheets?
Yes, VLOOKUP can search for duplicates across different sheets, as long as you reference the correct sheet and range in your formula.
What if I have multiple columns to check for duplicates?
You can check multiple columns for duplicates by using a combination of VLOOKUP and CONCATENATE or, in Excel 365, the TEXTJOIN function.

After identifying duplicates with VLOOKUP, you can manually delete them or use Excel’s ‘Remove Duplicates’ feature under the Data tab.
