title: Getting wrong output in xls/xlsx while converting it from csv
body: <p>So i've changed a csv to xls/xlsx but i'm getting one character per cell. I've used pipe(|) as a delimiter in my csv. 
  Here is one line from the csv:
  4.0|sdfa@sdf.nb|plplplp|plplpl|plplp|1988-11-11|M|asdasd@sdf.ghgh|sdfsadfasdfasdfasdfasdf|asdfasdf|3.4253242E7|234234.0|true|true|</p>
  
  <p>But in excel i'm getting as
  4 . 0 | s d f a </p>
  
  <p>Here's the code:</p>
  
  <pre><code>    try {
          String csvFileAddress = "manage_user_info.csv"; //csv file address
          String xlsxFileAddress = "manage_user_info.xls"; //xls file address
          HSSFWorkbook workBook = new HSSFWorkbook();
          HSSFSheet sheet = workBook.createSheet("sheet1");
          String currentLine=null;
          int RowNum=0;
          BufferedReader br = new BufferedReader(new FileReader(csvFileAddress));
          while ((currentLine = br.readLine()) != null) {
              String str[] = currentLine.split("|");
              RowNum++;
              HSSFRow currentRow=sheet.createRow(RowNum);
              for(int i=0;i&lt;str.length;i++){
                  currentRow.createCell(i).setCellValue(str[i]);
              }
          }
  
          FileOutputStream fileOutputStream =  new FileOutputStream(xlsxFileAddress);
          workBook.write(fileOutputStream);
          fileOutputStream.close();
          System.out.println("Done");
      } catch (Exception ex) {
          System.out.println(ex.getMessage()+"Exception in try");
      }
  </code></pre>
