            // Get the table of data for the first worksheet
            ExcelTable xlsFirstTable = ((ExcelWorksheet)workbook.easy_getSheetAt(0)).easy_getExcelTable();

            // Set the rich text value in cell
            xlsFirstTable.easy_getCell(1, 0).setHTMLValue(sFormattedValue);
            xlsFirstTable.easy_getCell(1, 0).setDataType(DataType.STRING);
            xlsFirstTable.easy_getCell(1, 0).setWrap(true);

            // Export Excel file
            System.out.println("Writing file: C:\\Samples\\Tutorial19 - RTF for Excel cells.xlsx");
            workbook.easy_WriteXLSXFile("C:\\Samples\\Tutorial19 - RTF for Excel cells.xlsx");

            // Confirm export of Excel file
