Well, as you have just seen there is a number of ways to find and remove duplicates in Excel, each having its strong points and limitations.
But what would you say if instead of those numerous duplicate removing techniques, you had one universal solution that wouldn't require memorizing a bunch of formulas and would work in all scenarios?
The good news is that such a solution does exist, and I will demonstrate it to you in the next and final part of this tutorial.
Unlike the inbuilt Excel Remove Duplicate feature, the Ablebits Duplicate Remover add-in is not limited to only removing duplicate entries. Like a Swiss knife, this multi-tool combines all essential use cases and lets you identify , select , highlight , delete , copy and move unique or duplicate values, absolute duplicate rows or partially matching rows, in 1 table or by comparing 2 tables, with or without first occurrences.
Assuming you have our Ultimate Suite installed in your Excel, perform these simple steps to eliminate duplicate rows or cells:.

Other values outside the range of cells or table will not change or move. When duplicates are removed, the first occurrence of the value in the list is kept, but other identical values are deleted. Because you are permanently deleting data, it's a good idea to copy the original range of cells or table to another worksheet or workbook before removing duplicate values.
If the range of cells or table contains many columns and you want to only select a few columns, you may find it easier to click Unselect All , and then under Columns , select those columns. Note: Data will be removed from all columns, even if you don't select all the columns at this step.
