        SaveFileDialog fichero = new SaveFileDialog();
        fichero.Filter = "Excel (*.xls)|*.xls";
        fichero.FileName = "export.xls";
        if (fichero.ShowDialog() == DialogResult.OK)
        {
            Microsoft.Office.Interop.Excel.Application aplicacion;
            Microsoft.Office.Interop.Excel.Workbook libros_trabajo;
            Microsoft.Office.Interop.Excel.Worksheet hoja_trabajo;
            aplicacion = new Microsoft.Office.Interop.Excel.Application();
            libros_trabajo = aplicacion.Workbooks.Add();
            hoja_trabajo =
                (Microsoft.Office.Interop.Excel.Worksheet)libros_trabajo.Worksheets.get_Item(1);

            // changing the name of active sheet
            hoja_trabajo.Name = "Exported from App";
            // storing header part in Excel
            for (int i = 1; i < grd.Columns.Count + 1; i++)
            {
                hoja_trabajo.Cells[1, i] = grd.Columns[i - 1].HeaderText;
            }

            //Recorremos el DataGridView rellenando la hoja de trabajo
            for (int i = 1; i < grd.Rows.Count + 1; i++)
            {
                for (int j = 0; j < grd.Columns.Count; j++)
                {
