7 Easy Steps To Highlight Duplicates In Google Sheets

If you’re managing data in Google Sheets, there’s a good chance you’ve encountered duplicates at some point. Maybe it’s a list of contacts, a sales report, or inventory data—duplicates can creep in, muddying your analysis and causing confusion. Fortunately, Google Sheets offers an easy way to highlight these duplicates so you can take quick action! Below, I’ll walk you through 7 easy steps to highlight duplicates effectively, along with tips, tricks, and common mistakes to avoid.

Step-by-Step Guide to Highlight Duplicates in Google Sheets

Step 1: Open Your Google Sheets Document

First things first! Open the Google Sheets document where you have your data. If you don’t have a document yet, create a new one and enter your data set that may contain duplicates.

Step 2: Select the Range of Data

Click and drag to highlight the range of data where you suspect duplicates may exist. This could be an entire column or a specific selection of cells within a row or column.

Step 3: Access the Conditional Formatting Menu

With your data selected, go to the menu bar at the top and click on Format. From the dropdown menu, select Conditional formatting. This will open a sidebar on the right-hand side of the screen.

Step 4: Set Up the Conditional Formatting Rule

In the Conditional Formatting sidebar, you'll see options to set your formatting rules. Under "Format cells if," select "Custom formula is" from the list.

Step 5: Enter the Formula

Now, enter the following formula to highlight duplicates:

=COUNTIF(A:A, A1) > 1

Make sure to replace A:A with the actual range of your selected data. For instance, if your duplicates are in column B, the formula should be =COUNTIF(B:B, B1) > 1. This formula checks the count of the current cell in the selected range and highlights it if it appears more than once.

Step 6: Choose Your Formatting Style

Next, decide how you want your duplicates to appear. Click on the "Formatting style" option and choose a fill color or text format. A vibrant fill color can draw attention to the duplicates, making them easy to spot! 🌈

Step 7: Click "Done"

After you’ve set your formatting preferences, click Done. You'll immediately see the duplicates highlighted in your selected range.

Additional Tips for Effective Duplicates Management

• Highlight Unique Values: If you’re interested in highlighting unique values instead, simply tweak your formula to =COUNTIF(A:A, A1) = 1.
• Apply Formatting to Additional Ranges: You can also highlight duplicates in multiple columns by using similar formulas for each column.
• Use Data Validation: To prevent duplicates in the future, consider using Data Validation by going to Data > Data validation, which allows you to set rules on what can be entered in a specific range.

Common Mistakes to Avoid

When working with conditional formatting, it’s easy to make mistakes. Here are some of the most common errors to look out for:

• Wrong Range Selection: Ensure you're selecting the right range that contains potential duplicates.
• Incorrect Formula Reference: Make sure that your formula correctly references the cells or ranges you intend to analyze.
• Not Adjusting for Different Columns: If you have data in various columns, you’ll need to adjust the formula accordingly to check the correct column.

Troubleshooting Issues

If your duplicates aren't highlighting as expected, consider these troubleshooting tips:

• Formula Errors: Double-check the formula syntax for any typos. Make sure you're not using any extra spaces.
• No Duplicates Found: Verify that the data you suspect to be duplicates actually contains them. Sometimes, leading or trailing spaces can prevent a match.
• Conditional Formatting Limits: Remember that Google Sheets has a limit on how many conditional formats you can apply. If you exceed this limit, some rules may not work.
