Working With Excel Files via COM

Applies to TestComplete 15.0, last modified on October 14, 2021

Sometimes, you may not be able to use the Excel object to work with Excel files. For example, you cannot use the object to work with ranges of cells, change cell formats, or work with cells containing formula expressions. In this case, you can work with Excel files by using the Excel COM server — Excel.Application. To get it in your tests, use the Sys.OleObject property or, if you use JavaScript, the getActiveXObject method.

For more information about the Excel OLE object model, see the Excel Object Model Overview article in the MSDN library.

The following code illustrates how you can read data from Excel cells by using the Excel OLE object and post this data to the TestComplete log:

JavaScript

function ReadDataFromExcel()
{
  let Excel = getActiveXObject("Excel.Application");
  Excel.Workbooks.Open("C:\\MyFile.xlsx");

  let RowCount = Excel.ActiveSheet.UsedRange.Rows.Count;
  let ColumnCount = Excel.ActiveSheet.UsedRange.Columns.Count;

  for (let i = 1; i <= RowCount; i++)
  {
    let s = "";
    for (let j = 1; j <= ColumnCount; j++)
      s += (VarToString(Excel.Cells.Item(i, j)) + "\r\n");
    Log.Message("Row: " + i, s);
  }

  Excel.Quit();
}

JScript

function ReadDataFromExcel()
{
  var Excel = Sys.OleObject("Excel.Application");
  Excel.Workbooks.Open("C:\\MyFile.xlsx");

  var RowCount = Excel.ActiveSheet.UsedRange.Rows.Count;
  var ColumnCount = Excel.ActiveSheet.UsedRange.Columns.Count;

  for (var i = 1; i <= RowCount; i++)
  {
    var s = "";
    for (var j = 1; j <= ColumnCount; j++)
      s += (VarToString(Excel.Cells(i, j)) + "\r\n");
    Log.Message("Row: " + i, s);
  }

  Excel.Quit();
}

Python

def ReadDataFromExcel():
  Excel = Sys.OleObject["Excel.Application"]
  Excel.Workbooks.Open("C:\\MyFile.xlsx")

  RowCount = Excel.ActiveSheet.UsedRange.Rows.Count
  ColumnCount = Excel.ActiveSheet.UsedRange.Columns.Count

  for i in range(1, RowCount + 1):
    s = "";
    for j in range(1, ColumnCount + 1):
      s = s + VarToString(Excel.Cells.Item[i, j]) + '\r\n'
    Log.Message("Row: " + VarToString(i), s);

  Excel.Quit();

VBScript

Sub ReadDataFromExcel
  Dim Excel, RowCount, ColumnCount, i, j, s

  Set Excel = Sys.OleObject("Excel.Application")
  Excel.Workbooks.Open("C:\MyFile.xlsx")

  RowCount = Excel.ActiveSheet.UsedRange.Rows.Count
  ColumnCount = Excel.ActiveSheet.UsedRange.Columns.Count

  For i = 1 To RowCount
    s = ""
    For j = 1 To ColumnCount
      s = s & VarToString(Excel.Cells(i, j)) & vbNewLine
    Next
    Log.Message "Row: " & i, s
  Next

  Excel.Quit
End Sub

DelphiScript

procedure ReadDataFromExcel;
var Excel, RowCount, ColumnCount, i, j, s;
begin
  Excel := Sys.OleObject('Excel.Application');
  Excel.Workbooks.Open('C:\MyFile.xlsx');

  RowCount := Excel.ActiveSheet.UsedRange.Rows.Count;
  ColumnCount := Excel.ActiveSheet.UsedRange.Columns.Count;

  for i := 1 to RowCount do
  begin
    s := '';
    for j := 1 to ColumnCount do
      s := s + VarToString(Excel.Cells(i, j)) + #13#10;
    Log.Message('Row: ' + VarToString(i), s);
  end;

  Excel.Quit;
end;

C++Script, C#Script

function ReadDataFromExcel()
{
  var Excel = Sys["OleObject"]("Excel.Application");
  Excel["Workbooks"]["Open"]("C:\\MyFile.xlsx");

  var RowCount = Excel["ActiveSheet"]["UsedRange"]["Rows"]["Count"];
  var ColumnCount = Excel["ActiveSheet"]["UsedRange"]["Columns"]["Count"];

  for (var i = 1; i <= RowCount; i++)
  {
    var s = "";
    for (var j = 1; j <= ColumnCount; j++)
      s += (VarToString(Excel["Cells"](i, j)) + "\r\n");
    Log["Message"]("Row: " + i, s);
  }

  Excel["Quit"]();
}

Samples

TestComplete includes a sample that demonstrates how to work with data stored in Excel files from scripts via the Excel.Application COM object:
