How can we implement a keyword driven automation framework in test complete for Desktop application?

See Excel Object, and it will be something similar to this

function PatientDetails()
{
    // Get the sheet of the Excel file
    var excelFile = Excel.Open("C:\\Temp\\PatientDetails.xlsx");
    var excelSheet = excelFile.SheetByTitle("Sheet1");
      
    // Write the obtained data into a new row of the file
    var rowIndex = excelSheet.RowCount + 1;
    excelSheet.Cell("A", rowIndex).Value = // GetPatientID;
    excelSheet.Cell("B", rowIndex).Value = // GetPatientName;
    excelSheet.Cell("C", rowIndex).Value = // GetPatientDOB;
    excelFile.Save();
}
