Highlight Duplicates in Google Sheets

In this tutorial, we’ll guide you through highlighting duplicate entries in Google Sheets. This technique is essential for managing data efficiently and ensuring accuracy.

Step 1: Open Your Google Sheet

Start by opening the Google Sheet that contains the data you want to examine.

Once you’re in your spreadsheet, make sure you know the specific column or range where you suspect duplicates might exist. This will help you focus your efforts.

Step 2: Select the Range

Highlight the cells where you want to check for duplicates.

Click and drag your mouse over the cells, or hold down the Shift key while selecting the range. It’s crucial to select the correct data range to ensure the duplicates are identified accurately.

Step 3: Open Conditional Formatting

Go to the menu and select Format, then choose Conditional formatting from the dropdown.

This will open a sidebar on the right side of your screen. Conditional formatting allows you to apply specific rules to your data, making it easy to spot duplicates.

Step 4: Apply Custom Formula

In the Conditional format rules panel, click on the "Format cells if" dropdown, select "Custom formula is," and enter the formula =COUNTIF(A:A, A1)>1.

This formula tells Google Sheets to highlight any cell that appears more than once in the selected range. Make sure to adjust the column letter to match your selected range.

Step 5: Choose the Highlighting Style

Pick a color or styling option to highlight duplicates, then click Done.

Choose a color that stands out against your data. Once you’ve selected your highlighting style, click "Done" to apply the format. Your duplicates should now be highlighted.

Once you’ve completed these steps, your Google Sheets will clearly display any duplicate entries, allowing you to address them as needed.
