How to remove duplicate values, considering a particular column and write it to other sheet.

2

give a try on following:

assign activity
LHS: dtCleansed
RHS:

(From d in YourDataTableVar.AsEnumerable
Group d by k=d(YourColBNameOrIndex).toString.trim into grp=Group
Where grp = 1
Select g =grp.First()).CopyToDataTable

it is removing all duplicates

in case of we want to keep also the first from the duplicates or others we can modify as well

Hi @nidhi.kowalli

Use the LINQ below to get the Unique values from the column!

dataTable = dataTable.AsEnumerable()
.GroupBy(Function(i) i.Field(Of String)(“columnWithDuplic”))
.Select(Function(g) g.First)
.CopyToDataTable
