export data to excel document with java

    appendToPane(tPane, "rangodofme: ", Color.BLACK);

    if (value of the[0].equals(report managed to [0]) && value of the[[1].equals(report managed to [1]))
        appendToPane(tPane, "V", darkGreen);
    else
        appendToPane(tPane, "X", Color.RED);
    appendToPane(tPane, "\t(Report: " + report managedto[0] + " - " + value of the[[1]
            + ", Checklist: " + rated values[0] + " - " + rated values[1] + ")\n", Color.BLUE);

I got an output like

rangodofme: X report: -73.0 -40 checklist : -72.0 -56

output is ok for me.

Right now I want this output in an excel sheet with 4 columns.
