using (ExcelEngine excelEngine = new ExcelEngine())
{
  IApplication application = excelEngine.Excel;
  application.DefaultVersion = ExcelVersion.Excel2013;

  //Open an existing XLTM file
  IWorkbook workbook = application.Workbooks.Open("Sample.xltm", ExcelOpenType.Automatic);

  //Save the file as XLSM
  workbook.SaveAs("Output.xlsm");
}
Using excelEngine As ExcelEngine = New ExcelEngine()
  Dim application As IApplication = excelEngine.Excel
  application.DefaultVersion = ExcelVersion.Excel2013

  'Open an existing XLTM file
  Dim workbook As IWorkbook = application.Workbooks.Open("Sample.xltm", ExcelOpenType.Automatic)

  'Save the file as XLSM
  workbook.SaveAs("Output.xlsm")
End Using
using (ExcelEngine excelEngine = new ExcelEngine())
{
  IApplication application = excelEngine.Excel;

  //Open an existing XLTM file
  Stream inputStream = new FileStream("Sample.xltm", FileMode.Open, FileAccess.Read);
  IWorkbook workbook = await application.Workbooks.OpenAsync(inputStream, ExcelOpenType.Automatic);

  //Save the file as XLSM
  FileSavePicker savePicker = new FileSavePicker();
  savePicker.SuggestedStartLocation = PickerLocationId.Desktop;
  savePicker.SuggestedFileName = "Output";
  savePicker.FileTypeChoices.Add("Excel Files", new List<string>() { ".xlsm" });
  StorageFile storageFile = await savePicker.PickSaveFileAsync();
  await workbook.SaveAsAsync(storageFile);
}
using (ExcelEngine excelEngine = new ExcelEngine())
{
  IApplication application = excelEngine.Excel;

  //Open an existing XLTM file
  FileStream inputStream = new FileStream("Sample.xltm", FileMode.Open, FileAccess.Read);
  IWorkbook workbook = application.Workbooks.Open(inputStream, ExcelOpenType.Automatic);

  //Save the file as XLSM
  FileStream outputStream = new FileStream("Output.xlsm", FileMode.OpenOrCreate, FileAccess.ReadWrite);
  workbook.SaveAs(outputStream);
  workbook.Close();
  excelEngine.Dispose();
}
using (ExcelEngine excelEngine = new ExcelEngine())
{
  IApplication application = excelEngine.Excel;

  //Open an existing XLTM file
  Assembly assembly = typeof(App).GetTypeInfo().Assembly;
  Stream fileStream = assembly.GetManifestResourceStream("App.Sample.xltm");
  IWorkbook workbook = application.Workbooks.Open(fileStream);

  //Save the file as XLSM
  MemoryStream stream = new MemoryStream();
  workbook.SaveAs(stream);

  stream.Position = 0;

  //Save the stream as a file in the device and invoke it for viewing
  Xamarin.Forms.DependencyService.Get<ISave>().SaveAndView("Output.xlsm", "application/vnd.ms-excel.sheet.macroEnabled.12", stream);
