Removing Duplicates

Removing Duplicates is used to find and remove duplicate entries, which is especially useful when working with data that contains duplicate rows or values.

Why Rows 2 and 4 Were Not Removed

Rows 2 and 4 contain unique data combinations, despite having the same values in the Name, Department, Salary columns. While the values in row 2 match those in row 4, the Employee ID is different. Since they do not match completely, they were not removed as duplicates.

You have an employee dataset in Google Sheets and want to remove duplicate records based on the Employee ID column. How should you proceed?
