HI @Pat_Wu

  • Use Read Range Workbook to read the excel.
  • Use a For Each Row in DataTable activity to iterate through each row in your DataTable.
  • Inside the loop, use an Assign activity to update the value in the “Price” column. You can use the Replace function to remove the dollar sign.
CurrentRow("Price") = CurrentRow("Price").ToString().Replace("$", "")
  • Inside the loop, use another Assign activity to convert Prices to Numbers:
CurrentRow("Price") = Convert.ToDouble(CurrentRow("Price").ToString())
  • Use the below syntax in Assign activity outside the loop.
maxPrice= dataTable.AsEnumerable().Max(Function(row) Convert.ToDouble(row("Price")))

DataType iof maxPrice is System.Double.

Hope it helps!!

Hi @Pat_Wu

For Each row In dt.Rows
    row("Price") = row("Price").ToString().Replace("$", "")
Next
maxPrice As Double = dt.AsEnumerable().Max(Function(row) CDbl(row("Price")))

Hope it helps!!

Hi you can try following

Max_Value = dt_Output.AsEnumerable().Max(Function(a) Convert.ToDouble(a(“Price”).ToString.Replace(“$”,“”)))

Max_Value is a variable type of System. Double

Max_Value = dt_Output.AsEnumerable().Max(Function(a) Convert.ToDouble(a(“Price”).ToString.Replace(“$”,“”)))
