How to Highlight Duplicates in Excel
In this tutorial, you’ll learn how to highlight duplicate values in an Excel spreadsheet step-by-step. This method ensures you can quickly spot any repetitive data entries.
Step 1: Open your Excel spreadsheet

Make sure the data you want to examine is neatly organized in columns or rows. This will make it easier to select the appropriate range of cells.
Step 2: Select the data range
Click and drag to select the range of cells you wish to check for duplicates.
If you’re working with a large dataset, you can click on the first cell, hold down the Shift key, and then click on the last cell to select the range quickly.

The Home tab is where you’ll find all the essential formatting tools, including Conditional Formatting.

This submenu contains various rules that you can apply to your selected cells, such as highlighting cells that contain certain values, dates, or text.
