Exportar a Excek con TAdvGridExcellO

Cuando intento configurar

procedure TFormListadoOPago.AdvGridExcelICellFormat(Sender: TAdvStringGrid;
  const GridCol, GridRow, XlsCol, XlsRow: Integer; const Value: WideString;
  var Format: TFlxFormat);
begin
  inherited;
  if (GridCol = 3) then Format.Format:='$ #,##0';
end;

No me reconoce TFlxFormat
al compilar me sale
[dcc32 Error] UListadoOPago.pas(551): E2003 Undeclared identifier: 'TFlxFormat'
uso Delphi 12.1 y la ultima version de VCL PAck
version 3.14 del AdvGridExcellO

Gracias
