Mira este ejemplo a ver si te sirve:

Código Delphi [-]
// 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;
