Hi,
I made application which needs to save the report file. I got report
file from the database and i got it as ResulSet.
I found in internet library calls CSVWriter which helps me save the
raport. The problem is that i dont know how to parse it to proper
Excel look.The code looks like this :

FileDialog d = new FileDialog(frame,"What file do you want to
save?",FileDialog.SAVE);
 d.setFile("*.csv");
 d.setDirectory(".");
 d.show();
 String saveFile;
 if((saveFile = d.getFile()) != null) {
    filename.setText(saveFile);
    directory.setText(d.getDirectory());
     try{
      CSVWriter writer = new CSVWriter(new
FileWriter(directory.getText()+filename.getText()), ',');
      writer.writeAll(rsDane2 , t);
      writer.close();
      }catch(java.sql.SQLException e){e.printStackTrace();}
      catch(java.io.IOException f){ f.printStackTrace(); }
 } else {
 filename.setText("You pressed cancel");
 directory.setText("");
 }

I would be greatfull for any help. Im looking for two solutions.
1) How can I convert saved csv file to Excel or diffrent type of file
( The prioritet is the data be visable ) Cause with comma i cant see
anything :(
2) Maybe there is diffrent way to save ResultSet to the excel file.
This is really big array so i think the best way is to save it in
excel file
