I hope this line of code helps you

 public String xls2text(InputStream in )throws Exception{  HSSFWorkbook excelWb = new HSSFWorkbook(in);
    StringBuffer result = new StringBuffer(8192);
    int numberOfSheets = excelWb.getNumberOfSheets();
    for (int i = 0; i < numberOfSheets; i++) {
        HSSFSheet sheet = excelWb.getSheetAt(i);
        int numberOfRows = sheet.getPhysicalNumberOfRows();
        if (numberOfRows > 0) {
            if (excelWb.getSheetName(i) != null
                    && excelWb.getSheetName(i).length() != 0) {
                // append sheet name to content
                if (i > 0) {
                    result.append("\n\n");
                }
                result.append(excelWb.getSheetName(i).trim());
                result.append(":\n\n");
            }

             for(int j=0;j<numberOfRows;j++) {
                HSSFRow row = sheet.getRow(i);
                if (row != null) {
                    boolean hasContent = false;
                    int  cellNumber = row.getPhysicalNumberOfCells();
                   for(int k=0;k<cellNumber;k++) {
                        HSSFCell cell = row.getCell(k);
                        String text = null;
                        try {
                            switch (cell.getCellType()) {
                            case HSSFCell.CELL_TYPE_BLANK:
                            case HSSFCell.CELL_TYPE_ERROR:
                                // ignore all blank or error cells
                                break;
                            case HSSFCell.CELL_TYPE_NUMERIC:
                                text = Double.toString(cell
                                        .getNumericCellValue());
                                break;
                            case HSSFCell.CELL_TYPE_BOOLEAN:
                                text = Boolean.toString(cell
                                        .getBooleanCellValue());
                                break;
                            case HSSFCell.CELL_TYPE_STRING:
                            default:
                                text = cell.getStringCellValue();
                                break;
                            }
                        } catch (Exception e) {
                        }
                        if ((text != null) && (text.length() != 0)) {
                            result.append(text.trim());
                            result.append(' ');
                            hasContent = true;
                        }
                    }
                    if (hasContent) {
                        result.append('\n');
                    }
                }
            }
        }
    }
    return result.toString();
