Pues entonces no hay ningún problema en la carpeta Demos de Delphi viene un ejemplo:

Código Delphi [-]
 procedure TfrmQR3Demo.rbFormLetterClick(Sender: TObject);
 begin
   Report := frmFormLetter.QuickRep1;
 end;
 
 // The following code show how to explicitly call an export
 // filter without going through the preview
 procedure TfrmQR3Demo.btnExportClick(Sender: TObject);
 begin
   btnExport.Enabled := False;
   with SaveDialog1 do
   begin
     if Execute then
     begin
       frmFormLetter.QuickRep1.ExportToFilter(TQRCommaSeparatedFilter.Create(FileName));
 {
 Other filters:
 HTML: TQRHTMLDocumentFilter
 ASCII: TQRAsciiExportFilter
 CSV: TQRCommaSeparatedFilter
 
 In Professional Version:
 RTF: TQRRTFExportFilter
 WMF: TQRWMFExportFilter
 Excel: TQRXLSFilter
 }
     end;
   end;
   btnExport.Enabled := True;
 end;
