Writing Data in Excel Files

Applies to TestComplete 15.0, last modified on November 17, 2021

When you use Excel files as data storages, you may need to change existing data or add new rows to these files. The recommended approach depends on your test type:

In Keyword Tests

Note: To work with Excel files in your tests, you do not need to have Microsoft Office Excel installed on your computer.

You can use the following operations, to write data to Excel files:

  • Excel - Write Value – Writes data to the specified Excel cell.

  • Excel - Add Row – Adds a row with specified data below the last non-empty line of the Excel sheet.

Excel - Write Value operation

Follow the steps below to write data to the specified Excel cell:

  1. Add the Excel - Write Value operation to your keyword test. TestComplete will display the Operation Parameters wizard.

  2. On the first page of the wizard, specify Excel parameters.

    • In the File Name edit box, click the ellipsis button. In the Value edit box of the subsequent dialog, specify the fully qualified file name of your Excel file.

      Click OK.

    • In the Cell edit box, select a cell to which data will be written. If the file is loaded correctly, the Cell edit box displays the content of the file. You can select the desired sheet and cell or specify it manually (for instance, Sheet1!B3).

      Note: If the manually specified sheet does not exist, TestComplete creates it and writes data to the corresponding cell.
    • In the Value edit box, type the desired value manually or click the ellipsis button and use the subsequent Operation Parameters dialog.

    Click Next.

  3. On the next page of the wizard, review the parameters you have created and change them if needed.

    Click Finish. TestComplete will add the operation to your test.

Excel - Add Row operation

Follow the steps below to write data to add a row with specified data below the last non-empty line of the Excel sheet:

  1. Add the Excel - Add Row operation to your keyword test. TestComplete will display the Operation Parameters wizard.

  2. On the first page of the wizard, specify Excel parameters.

    • In the File Name edit box, click the ellipsis button. In the Value edit box of the subsequent dialog, specify the fully qualified file name of your Excel file.

      Click OK.

    • In the Sheet edit box, select a sheet to which a row will be added. If the file is loaded correctly, the Sheet edit box displays the existing sheets. You can select the desired sheet or specify it manually.

      Note: If the manually specified sheet does not exist, TestComplete creates it and adds the row to the corresponding sheet.
    • Click Add to specify columns to which new values will be added. In the Value rows, type the desired values manually or click the ellipsis button and use the subsequent Operation Parameters dialog.

      If needed, click Remove to remove the last added column with the corresponding value.

    Click Next.

  3. On the next page of the wizard, review the parameters you have created and change them if needed.

    Click Finish. TestComplete will add the operation to your test.

Excel - Add Row operation
Operation Notes:
  • The target Excel file must not be opened in third-party programs during operation executions.

  • Excel files secured with passwords are not supported.

  • Operations save changes to Excel files during their executions, you do not need to add additional operations for these purposes.

In Script Tests

Note: To work with Excel files in your tests, you do not need to have Microsoft Office Excel installed on your computer.

To write data to Excel cells, use the Excel runtime object:

JavaScript, JScript

function ExcelExample()
{
  // Get the sheet of the Excel file
  var excelFile = Excel.Open("C:\\temp\\DataStorageExcel.xlsx");
  var excelSheet = excelFile.SheetByTitle("Sheet1");
  
  // Read data from the Excel file
  var valueA = excelSheet.Cell("A", 3).Value;
  var valueB = excelSheet.Cell(2, 3).Value;
  var valueC = excelSheet.CellByName("C3").Value;
  
  // Write the obtained data into a new row of the file
  var rowIndex = excelSheet.RowCount + 1;
  excelSheet.Cell("A", rowIndex).Value = valueA;
  excelSheet.Cell(2, rowIndex).Value = valueB;
  excelSheet.Cell("C", rowIndex).Value = valueC;
  
  // Save the file to apply the changes
  excelFile.Save();
  
  // Save the file with another name
  // excelFile.SaveAs("C:\\temp\\DataStorageExcel_new.xlsx");
}

Python

def ExcelExample():
  
  # Get the sheet of the Excel file
  excelFile = Excel.Open("C:\\temp\\DataStorageExcel.xlsx")
  excelSheet = excelFile.SheetByTitle["Sheet1"]
  
  # Read data from the Excel file
  valueA = excelSheet.Cell["A", 3].Value
  valueB = excelSheet.Cell[2, 3].Value
  valueC = excelSheet.CellByName["C3"].Value
  
  # Write the obtained data into a new row of the file
  rowIndex = excelSheet.RowCount + 1
  excelSheet.Cell["A", rowIndex].Value = valueA
  excelSheet.Cell[2, rowIndex].Value = valueB
  excelSheet.Cell("C", rowIndex).Value = valueC

  # Save the file to apply the changes
  excelFile.Save()
  
  # Save the file with another name
  # excelFile.SaveAs("C:\\temp\\DataStorageExcel_new.xlsx")

VBScript

Sub ExcelExample
  Dim excelFile, excelSheet, valueA, valueB, valueC, rowIndex
  
  ' Get the sheet of the Excel file
  Set excelFile = Excel.Open("C:\temp\DataStorageExcel.xlsx")
  Set excelSheet = excelFile.SheetByTitle("Sheet1")
  
  ' Read data from the Excel file
  valueA = excelSheet.Cell("A", 3).Value
  valueB = excelSheet.Cell(2, 3).Value
  valueС = excelSheet.CellByName("C3").Value
  
  ' Write the obtained data into a new row of the file
  rowIndex = excelSheet.RowCount + 1
  excelSheet.Cell("A", rowIndex).Value = valueA
  excelSheet.Cell(2, rowIndex).Value = valueB
  excelSheet.Cell("C", rowIndex).Value = valueC
  
  ' Save the file to apply the changes
  excelFile.Save()
  
  ' Save the file with another name
  ' excelFile.SaveAs("C:\temp\DataStorageExcel_new.xlsx")
End Sub

DelphiScript

procedure ExcelExample;
var
  excelFile, excelSheet, valueA, valueB, valueC, rowIndex;
begin
  // Get the sheet of the Excel file
  excelFile := Excel.Open('C:\\temp\\DataStorageExcel.xlsx');
  excelSheet := excelFile.SheetByTitle('Sheet1');
  
  // Read data from the Excel file
  valueA := excelSheet.Cell('A', 3).Value;
  valueB := excelSheet.Cell(2, 3).Value;
  valueC := excelSheet.CellByName('C3').Value;
  
  // Write the obtained data into a new row of the file
  rowIndex := excelSheet.RowCount + 1;
  excelSheet.Cell('A', rowIndex).Value := valueA;
  excelSheet.Cell(2, rowIndex).Value := valueB;
  excelSheet.Cell('C', rowIndex).Value := valueC;
  
  // Save the file to apply the changes
  excelFile.Save();
  
  // Save the file with another name
  // excelFile.SaveAs('C:\\temp\\DataStorageExcel_new.xlsx');
end;

C++Script, C#Script

function ExcelExample()
{
  // Get the sheet of the Excel file
  var excelFile = Excel["Open"]("C:\\temp\\DataStorageExcel.xlsx");
  var excelSheet = excelFile["SheetByTitle"]("Sheet1");
  
  // Read data from the Excel file
  var valueA = excelSheet["Cell"]("A", 3)["Value"];
  var valueB = excelSheet["Cell"](2, 3)["Value"];
  var valueC = excelSheet["CellByName"]("C3")["Value"];
  
  // Write the obtained data into a new row of the file
  var rowIndex = excelSheet["RowCount + 1"];
  excelSheet["Cell"]("A", rowIndex)["Value"] = valueA;
  excelSheet["Cell"](2, rowIndex)["Value"] = valueB;
  excelSheet["Cell"]("C", rowIndex)["Value"] = valueC;
  
  // Save the file to apply the changes
  excelFile["Save"]();
  
  // Save the file with another name
  // excelFile["SaveAs"]("C:\\temp\\DataStorageExcel.xlsx");
}

In some advanced cases, for instance, when you work with ranges of cells in Excel files, you can use the Excel.Application COM object.

Note: Microsoft Office Excel must be installed on your computer.
