  1. First use Read Range activity to read the data from Excel and will give you output as Datatable and say DT.

  2. And then try below expression.

             String sumOfColumn = DT.AsEnumerable.Sum(Function(x) Convert.ToDouble(x(“ColumnName”).ToString.Trim) ).ToString

  3. And then write into excel file.
