7 Easy Steps To Highlight Duplicates In Google Sheets

If you've ever worked with data in Google Sheets, you know how crucial it is to ensure that your information is accurate and free from duplicates. Duplicates can cause confusion, misinterpretations, and even errors in calculations. Thankfully, Google Sheets offers an easy and effective way to highlight duplicates, making your data cleaner and easier to analyze. In this guide, we'll walk you through 7 easy steps to highlight duplicates in Google Sheets, along with some helpful tips and tricks. Let’s get started! 🥳

Step 1: Open Your Google Sheets Document

First things first, you'll need to open the Google Sheets document where you want to check for duplicates. If you're working with a new sheet, simply create it or upload a CSV file that contains your data.

Step 2: Select the Range of Data

Once your document is open, select the range of cells where you want to find duplicates. Click and drag your mouse to highlight the desired range or use the shift key to select multiple cells.

<table> <tr> <th>Option</th> <th>Description</th> </tr> <tr> <td>Single Column</td> <td>Select a single column to search for duplicates within that column.</td> </tr> <tr> <td>Multiple Columns</td> <td>Select multiple columns if you want to check for duplicates across different columns.</td> </tr> </table>

Step 3: Access Conditional Formatting

Now that you've selected your data, it's time to use Conditional Formatting. Go to the top menu and click on Format > Conditional formatting. A sidebar will pop up on the right side of your screen.

Step 4: Set the Formatting Rule

In the sidebar, under the "Format rules" section, click on the drop-down menu. Select "Custom formula is" from the list of options. This allows you to create a custom formula that will help you highlight duplicates.

Step 5: Enter the Duplicate Formula

In the formula field, enter the following formula:

=COUNTIF(A:A, A1) > 1

Make sure to replace A:A with the range you selected, and A1 with the first cell of your selected range. This formula counts how many times the value in the selected cell appears in the column. If it’s greater than 1, it means it's a duplicate.

Step 6: Choose Your Formatting Style

Next, scroll down in the sidebar to find the "Formatting style" section. Here, you can choose how you want the duplicates to be highlighted. You can change the background color, text color, or even add bold text to make duplicates stand out. Use a color that contrasts well with your data to ensure that duplicates are easily visible. 🎨

Step 7: Click "Done" and Review Your Sheet

Once you’ve set your formatting, click the Done button at the bottom of the sidebar. The duplicates in your selected range will now be highlighted based on the formatting style you chose. Take a moment to review your sheet to ensure that the duplicates are clearly marked.

Common Mistakes to Avoid

• Not Updating Cell References: Be sure to adjust the formula references correctly. If you're working on a different column or range, the formula needs to reflect that.

• Ignoring Formatting Styles: If you don’t choose a noticeable formatting style, the duplicates may not stand out as much as you’d like.

• Not Double-Checking Your Data: After highlighting duplicates, it’s always a good idea to double-check your data for any accidental duplicates you may have missed!

Troubleshooting Issues

If your duplicates aren’t highlighting as expected, try these troubleshooting steps:

• Recheck the Formula: Make sure there are no typos and that the cell references match your selection.
• Ensure Correct Data Types: Sometimes, numbers stored as text won’t match numbers, so ensure your data types are consistent.
• Refresh Google Sheets: Sometimes a refresh can solve minor glitches. Simply reload the page and check if the duplicates are highlighted.
