Reading/Writing Excel -without POI

Question

dear friends,
I would like to know whether it would be possible to read from/write to excel files using some API other than POI.
would such an API support formula evaluation? I am in need of urgent help.

Answer 1

Workbook workbook = Workbook.getWorkbook(new File("C:\\\\PO_CIRCLE_07Q1.xls"));
              Sheet sheet = workbook.getSheet(0);
              Cell arr [] = sheet.getRow(0);
              Cell arr1[] = sheet.getColumn(0);
              int length_Row = arr.length;
              int length_Column = arr1.length;
              for(int i = 0; i <= length_Column - 1; i++){
                 arr = sheet.getRow(i);
                 if(arr[1].getContents().equals(".")){
                      continue;
                 if( (arr[1].getContents() != "") ){
                    for(int j = 0; j <= length_Row - 1; j++){
                        Cell c1 = sheet.getCell(j,i);
                        String s = c1.getContents();
                            if(j < length_Row - 1){
                              System.out.print(s + ",");
                              pw.print(s + ",");
                              pw.flush();  
                            else{
                                System.out.println(s);
                                pw.println(s);
                                pw.flush();
          }catch(Exception e){
               e.printStackTrace();
          }This is the code used to read and write the contents of the excel file.
I am using getContents() method of class Cell which returns the contents of the cell as a string. what is bothering me is that for formula cells the exact output is not obtained.
Suppose, the excel file's G6 cell contains 22.58 and G7 has a formula value 4 and the formula for it is =+G6*16%.
In the excel file only 4 is present in G7 whereas the program is printing it out to be 3.613(approx.).
Why is it so?
NOTE: For the formula =+G6*16% the real value should be less than 4.
