function AppendObject(obj) {
    //console.log(JSON.stringify(obj) + ":" + JSON.stringify(obj).length);

    var Summary = null;

function Convert() {
    $(".data").empty();
    var ParsedJSON = $.parseJSON($("textarea").val()),
        ObjectArray = [],
        Summaries = [];

    if (!(ParsedJSON instanceof Array)) ObjectArray[0] = ParsedJSON;
    else ObjectArray = ParsedJSON;

    for (var i = 0; i < ObjectArray.length; i++) Summaries[Summaries.length] = AppendObject(ObjectArray[i]);

    $(".data").text(JSON.stringify(Summaries));
