5 Easy Steps To Mark Duplicates In Google Sheets

Google Sheets has become an indispensable tool for managing data, whether you’re tracking expenses, organizing contact lists, or analyzing research. One common issue that users encounter is dealing with duplicates. Identifying and marking duplicate entries in your spreadsheet can save you time and prevent confusion. In this post, we’ll walk through 5 easy steps to mark duplicates in Google Sheets, and share helpful tips, shortcuts, and advanced techniques along the way. Let's dive in! 🚀

Step 1: Open Your Google Sheets Document

Before we can mark duplicates, we need to ensure you have the correct document open. If you don’t have a Google Sheets document yet, you can create one by going to Google Drive and clicking on the "+ New" button.

Step 2: Select the Range of Data

Once your document is open, it's time to select the range of data where you suspect duplicates might exist. You can click and drag your mouse to select the cells, or simply click on the first cell, hold down Shift, and then click on the last cell in the range.

Quick Tip: You can select entire columns by clicking on the column letter at the top!

Step 3: Open Conditional Formatting

Conditional Formatting allows you to automatically apply formatting to cells based on specific criteria. Here’s how to access it:

1. Click on the “Format” menu at the top of the page.
2. Choose “Conditional formatting” from the dropdown menu.

This opens a panel on the right side of your screen where you can set the rules for marking duplicates.

Step 4: Set Up the Duplicates Rule

Now that you have the conditional formatting panel open, follow these steps to set up the rule to highlight duplicates:

1. Under the “Format cells if…” section, select “Custom formula is”.

2. In the text box that appears, enter the following formula:

   =countif(A:A, A1) > 1
   

   Make sure to replace A:A and A1 with your actual data range. If your data starts from column B, for instance, you should use B:B and B1.

3. Choose a formatting style (like a background color or text color) to apply to duplicates. This will help you easily identify them! 🟡

4. Click on “Done”.

Now all duplicates in your selected range will be highlighted according to the formatting style you chose.

Step 5: Review and Clean Up Your Data

With your duplicates marked, take a moment to review them. You can either:

• Remove the duplicates: If duplicates are unnecessary, you can delete the extra entries.
• Keep them marked: If they serve a purpose, just leave them highlighted for your records.

Common Mistakes to Avoid

• Not selecting the correct range: Make sure you only select the data where you want to find duplicates.
• Using the wrong formula: Double-check your formula to ensure it matches your selected column.
• Overlooking the formatting options: Sometimes we forget to apply a clear, contrasting format. Choose something that stands out!

Troubleshooting Issues

If duplicates aren't highlighting as expected, check the following:

• Ensure your formula correctly references the range.
• Make sure your formatting is set up properly.
• Double-check that you don’t have leading/trailing spaces in your entries, as these can prevent duplicates from being detected.
