Python

def ColumnName():
  # Specifies two new Excel drivers 
  Driver = DDT.ExcelDriver("C:\\MyFiles\\1.xls", "Sheet1");
  ColNum = Driver.ColumnCount;
  # Iterates through the columns 
  for i in range(0, ColNum):
    ColName = Driver.ColumnName[i]
    # Posts a column name to the test log 
    Log.Message("The name of the " + str(i + 1) + " column is: " + str(ColName))

    ColName = Driver.ColumnName(i)
    ' Posts a column name to the test log
    Log.Message("The name of the " & (i+1) & " column is: " & ColName)
  Next
  
End Sub

DelphiScript

  // Specifies two new Excel drivers
  Driver := DDT.ExcelDriver('C:\MyFiles\1.xls', 'Sheet1');
  ColNum := Driver.ColumnCount;
  
  // Iterates through the columns
  for i := 0 to (ColNum - 1) do
  begin
    ColName := Driver.ColumnName[i];
    // Posts a column name to the test log
