private String getCellValue(HSSFCell cell) {
		String cellValue = "";
		DecimalFormat df = new DecimalFormat("#");
		switch (cell.getCellType()) {
		case HSSFCell.CELL_TYPE_STRING:
			cellValue = cell.getRichStringCellValue().getString().trim();
			break;
		case HSSFCell.CELL_TYPE_NUMERIC:
			cellValue = df.format(cell.getNumericCellValue()).toString();
			break;
		case HSSFCell.CELL_TYPE_BOOLEAN:
			cellValue = String.valueOf(cell.getBooleanCellValue()).trim();
			break;
		case HSSFCell.CELL_TYPE_FORMULA:
