I demonstrate how to efficiently remove duplicate data in Excel using Power Query. I start the tutorial by explaining why traditional methods, like conditional formatting, might not always be effective for finding duplicates, specifically when there is no unique primary key.

I then discuss how to use the 'Remove Duplicates' feature under the Data tab, highlighting its benefits and limitations. For a more dynamic solution, I guide you through the application of Power Query to delete duplicate records.

This approach allows the file to continuously update itself even when new data is introduced, thus automatically maintaining the removal of duplicates. This video is for both beginners looking for a basic guide to check for duplicates in Excel and experienced users seeking an advanced and automated way to maintain data integrity.
