We have multiple ways to delete duplicate values in excel. We have remove duplicate option itself in 2007 Excel version or higher versions. If we need to delete manually in the sense, we have to follow below methods to do this.
- Sort data either in A to Z or Z to A methodology in the required column
- Next to that column keep formula = currentcell = Below cell.
(Note: For example if you need to identify duplicate values in the 1st column. Then in the 2nd column, in cell B1 you need to keep the formula as =A1=A2, then drag this till end of the data of the 2nd column)
- If you get TRUE as result in the cells of 2nd column, those all are duplicates. You can just filter those to delete.
Assume that you have to find duplicates in the 1st Column, then just select B1 cell and keep formula as “=Countif(A:A,A1). Then drag this till ending data cell of 1st Column. If you get more than one as number in the 2nd Column, those all are duplicates. Now you can delete by filtering
