How to Highlight Duplicates in Excel

If you are working with a large dataset in Excel, it can be difficult and time-consuming to manually identify duplicates. Luckily, Excel offers a quick and straightforward way to highlight duplicates within a range of cells. By using Excel’s conditional formatting feature, you can easily identify and highlight both exact and partial matches. In this blog post, we will guide you through the steps required to highlight duplicates in Excel, allowing you to save time and work more efficiently.

Introduction

Duplicates in Excel can be confusing and annoying, especially if you’re working with a large dataset. This process can be made easier with conditional formatting, a feature that allows you to customize how cells appear based on their contents.

Step 1: Select the Data Range

Start by selecting the range of data where you want to highlight duplicates. You can do this by clicking and dragging over the cells that contain the data you want to work with.

Step 2: Open Conditional Formatting

To open the conditional formatting menu, select the “Conditional Formatting” option from the “Home” tab in the Excel ribbon. Then, select “Highlight Cells Rules” and choose “Duplicate Values” from the dropdown menu.

Step 3: Choose Formatting Style

Now you’ll need to choose the formatting style for the duplicate values. You can select from preset styles, or you can create your own custom style. You can also choose whether to highlight exact matches only or partial matches as well.

Step 4: Review Your Data Range

Once you’ve selected your formatting style, it’s important to review your data range to make sure everything is correct. If you need to make any changes, click on “Conditional Formatting” again and select “Manage Rules.”

Step 5: View Your Highlighted Duplicates

After you’ve made any necessary changes, you can click “OK” to close the formatting menu. Your duplicates should now be highlighted, allowing you to quickly identify and review them.

Additional Tips

When using conditional formatting, keep these tips in mind:

• You can easily remove highlight duplicates by selecting “Clear Rules” in the conditional formatting menu.
• You can also specify how many duplicate values should be considered as duplicates by selecting “More Rules” in the conditional formatting menu.

Conditional Formatting for Partial Matches

If you would like to highlight partial matches as well as exact matches, there is an additional step in the conditional formatting process. After selecting “Duplicate Values” in the “Highlight Cells Rules” dropdown menu, select “Custom Format.”

Then, choose whether you want to highlight values that contain or do not contain a specific text string. You can also specify the font color, background color, and other formatting options for partial matches.

Conditional Formatting for Specific Duplicate Values

If you only want to highlight specific values that are duplicated, you can do so by using a formula in the conditional formatting menu. Select “Use a formula to determine which cells to format” instead of “Duplicate Values” in the “Highlight Cells Rules” dropdown menu. Then, enter the formula that identifies the specific values you want to highlight. For example, the formula “=COUNTIF($A$1:$A$10,A1)>1” will highlight all cells in range A1:A10 that contain duplicate values.

Removing Duplicate Values

If you’ve highlighted your duplicates, you may want to remove them from your dataset. You can do this by selecting the affected cells and clicking “Data” > “Remove Duplicates” in the Excel ribbon. Here you can choose which columns to check for duplicates and which columns to keep for your final dataset.

Highlighting duplicates in Excel is a simple process that can save you time and effort when working with large datasets. By using Excel’s conditional formatting feature, you can easily identify and review both exact and partial matches, and remove duplicates if necessary. With these tips in mind, you’ll be able to work more efficiently and keep your data clean and organized.
