How To Delete Duplicate Values in Microsoft Excel
Eliminating duplicate values in Microsoft Excel is essential for data accuracy and analysis efficiency. Below is our guide to swiftly eliminate redundant entries and maintain a clean dataset.
-
Step 1. Select Your Data
Start by selecting the range of cells, or the entire table, where you suspect duplicates might exist in your sheet. Clicking on the top-left cell and dragging down to the bottom-right cell will ensure you’ve covered the area you want to clean.

Step 2. Open the Data Tools Menu
Navigate to the “Data” tab on Excel’s ribbon. Here, you’ll find various tools for managing your spreadsheet’s data. Look for the “Remove Duplicates” button within the “Data Tools” group.

Step 3. Specify Columns for Duplicate Criteria
Upon clicking “Remove Duplicates,” a dialog box will appear. You’ll see a list of all columns within your selected range. Check the boxes next to the columns you want to check for duplicates. If you’re working with a full table, checking “My data has headers” will ensure your column titles are not considered in the duplicate search.

After selecting the relevant columns, click “OK” to proceed. Excel will process your data, removing duplicate rows matching your criteria across the selected columns. A confirmation dialog will appear, indicating how many duplicates were found and removed, and how many unique values remain.
