Excel Remove Duplicates vs Advanced Filter – Clean Data Fast and Smart

Data Cleaning Made Easy in Excel with Remove Duplicates and Advanced Filters

Working with large datasets in Microsoft Excel often leads to repeated entries that can distort results and slow down analysis. Luckily, Excel gives you two powerful tools to handle this fast — Remove Duplicates and Advanced Filter. Both serve different purposes: one cleans the data permanently, the other lets you filter and copy unique values without altering the original sheet.

🧹 What Is Remove Duplicates in Excel?

The Remove Duplicates feature is a quick way to clean your spreadsheet by deleting duplicate rows. It’s perfect when you want a definitive master list or when preparing a clean dataset for dashboards or reports.
