Convert one data structure of nested javascript objects to nested arrays

I am trying to convert a JSON string to a Javascript object literal. I think this is possible with some loops, but I could not do it. The target structure is shown below, "chartData".

The script can be found here: http://jsbin.com/ajemih/13/edit

Here is the JSON data:

{
   "1b":{
      "allLoad":"130",
      "loadMovement":"111",
      "allMovement":"111"
   },
   "1a":{
      "allLoad":"910",
      "loadMovement":"671",
      "allMovement":"280"
   },
   "systemLoad":"963"
}

It should look like this after the conversion:

chartData = [[['loadMovement', 111], 
              ['allMovement', 120], 
              ['allLoad', 130]], 
             [['Load+Move', 671], 
              ['allMovement', 280], 
              ['allLoad', 910]]];

I think this will work:

Working demo: http://jsfiddle.net/jfriend00/YmjDR/

var data = {
   "1b":{
      "allLoad":"130",
      "loadMovement":"111",
      "allMovement":"111"
   },
   "1a":{
      "allLoad":"910",
      "loadMovement":"671",
      "allMovement":"280"
   },
   "systemLoad":"963"
};

var chartData = [];

for (var i in data) {
    var item = data[i];
    var outer = [];
    // skip over items in the outer object that aren't nested objects themselves
    if (typeof item === "object") {
        for (var j in item) {
            var temp = [];
            temp.push(j);
            temp.push(item[j]);
            outer.push(temp);
        }
    }
    if (outer.length) {
        chartData.push(outer);
    }
}

You can do something like this:

var chartData = []

for(var key in data) {        
    var properties = data[key];

    if(typeof properties === "object") {
       var array = [];

       for(var propKey in properties) {
           array.push([propKey, properties[propKey]])
       }

       chartData.push(array);
    }             
}

Take a look at the fiddle .

var jsonData = 'your json string';

Object.keys( jsonData ).map(function( key ) {
    if( typeof jsonData[ key ] === 'object' ) {
        return Object.keys( jsonData[ key ] ).sort(function( a, b ) {
            return +jsonData[ key ][ a ] - +jsonData[ key ][ b ];
        }).map(function( name ) {
            return [ name, jsonData[ key ][ name ] ];
        });
    }
}).filter( Boolean );
