hi, welcome to the forum

First, let’s get repetitive values only to array of string
arr = (From row In dt
Group row By k=row("ColName").ToString.Trim Into grp=Group
Where grp.Count >1
Select r = grp(0)("ColName").ToString).ToArray

Second, let’s find indexes of rows in dt , that should be colored (also array of string)
rows_to_color = (From row In dt
Where Array.IndexOf(arr, row("ColName").ToString) > -1
Select val = dt.Rows.IndexOf(row).ToString).ToArray

Than use Set Range Color activity :grinning:
