Assign Activity
dtResult | DataType: DataTable = dtOrigVar.Clone

Assign Activity
dtResult =

Group d by k=d("id").toString.Trim into grp=Group
let ra1 = grp.First().ItemArray.SkipLast(1).Cast(of Object)
Let tj = String.Join(",", grp.Select(Function (g) g("token"))
Let ra = ra1.Append(tj).toArray
Select r = dtResult.Rows.Add(ra)).CopyToDataTable

we grouped the data on id and used the aggregated tokens from the groupmembers

Hi @Nisha_K21

=> Use Read Range Workbook to read the excel and store the output in a data table say InputDt.

=> Use the below syntax in Assign activity:

OutputDt = (From row In InputDt.AsEnumerable()
 Group row By id = row("id"), name = row("name"), email = row("email") Into Group
 Select InputDt.Clone.Rows.Add(id, name, email, String.Join(",", Group.Select(Function(r) r("token").ToString())))).CopyToDataTable()

OutputDt is of DataType System.Data.DataTable

=> Use Write Range Workbook to write the OutputDt back to excel.
