Writing Files to Excel in AS3

Hi,

i have a game that automatically records players interactions. Now I want to write the data to an excel file and use the formular functions of excel.

I was able to write to cvs file but I am aware I cant use the excel formular with this approach.

what do I need to do?

here is the code:

//in spacegame class

public var file:File = File.desktopDirectory.resolvePath( "LogOutput_2Player_1Cannons_DANCEMAT.xlsx" );

public var stream:FileStream = new FileStream();

                    public function logString(s:String): void

                    {

                              var today = new Date();

                              stream.open(file,FileMode.APPEND);

                              stream.writeUTFBytes(today.getDate()+"/"+(today.getMonth()+1)+"/"+today.getFullYear()+ "-" +today.getHours()+":"+today.getMinutes()+ ":"+today.getSeconds());

                              stream.writeUTFBytes(":"+s+"\r\n");

                              stream.close();

}

//in player class

private function onKeyPress(evt:KeyboardEvent)

                    {

                              if (evt.keyCode == 39 )

                              {

                                        rightArrow = true;

                                        spacegame.instance.rightCircle.visible = true;

                                        spacegame.instance.logString("Player 1 PRESSES RIGHT KEY");

}

}

when you run the game and player interact , an excel file is created with this data in it:

here it is in one column but I want the file to put the date in one column, the time in one column, player1 in one column and presses right ke in one column
