How to Conditional Formatting Duplicates in Google Sheets

Conditional formatting in Google Sheets is a powerful feature that allows you to highlight or format cells based on specific conditions. One common use case is to identify and highlight duplicate values within a range of cells. This can be particularly useful when analyzing large datasets or when you want to quickly spot any inconsistencies or errors. In this article, we will guide you through the steps to apply conditional formatting to duplicates in Google Sheets.

Step 1: Select the Range

The first step in conditional formatting duplicates is to select the range of cells you want to analyze. This can be a single column, multiple columns, or an entire sheet. Once you have selected the range, click on the “Format” menu at the top of the screen and choose “Conditional formatting” from the dropdown menu.

Step 2: Create a New Rule

After selecting “Conditional formatting,” a dialog box will appear with various options. Click on the “+” button to create a new rule. This will open a new window where you can define the conditions for the formatting.

Step 3: Set the Condition

In the new rule window, you will see a dropdown menu for selecting the type of condition you want to apply. Choose “Duplicate values” from the list. This will allow you to identify cells with duplicate values within the selected range.

Step 4: Customize the Formatting

Once you have selected the condition, you can customize the formatting options. Google Sheets provides a variety of formatting options, such as font color, background color, borders, and more. You can choose the formatting that best suits your needs and preferences.

Step 5: Apply the Formatting

After customizing the formatting, click the “Save” button to apply the conditional formatting rule to the selected range. Google Sheets will automatically highlight the cells with duplicate values according to the formatting options you have chosen.

Step 6: Modify or Delete the Rule

If you need to modify or delete the conditional formatting rule, simply click on the rule you want to edit or delete in the conditional formatting dialog box. You can then make the necessary changes or click the “Delete” button to remove the rule entirely.

Conclusion
