Convert json to array via javascript

Possible duplicate:
JSON to javaScript array

Can someone tell me how I can convert json data to an array using a java script to draw a diagram from the data. JSON is structured as follows:

{
"d":{
  "results":[
     {
       "_metadata":{
          "uri": "http://www.something.com/hi",
          "type" : "something.preview.hi"
          }, "Name", "Sara", "Age": 20, "Sex" : "female"
     },
       "_metadata":{
           "uri": "http://www.something.com/hi",
           "type" : "something.preview.hi"
          }, "Name", "James", "Age": 20, "Sex" : "male"
     } 
   ]
  }
}

I would like to convert this jason to the following format:

var sampleData = [
                { name: 'Sara', Age: 20, Sex: 'female'},
                { name: 'James', Age: 20, Sex: 'male'}
            ];

Does anyone have any tips on how to achieve this?

var sampleData = [], results = d.results;
for (var i = 0, len = results.length; i < len; i++) {
    var result = results[i];
    sampleData.push({ name: result.Name, Age: result.Age, Sex: result.Sex });
}

You just need to iterate the array of results in your javascript object and create a new array that has the data in the desired format.

var results = data.d.results;
var sampleData = [], item;
for (var i = 0, len = results.length; i < len; i++) {
    item = results[i];
    sampleData.push({name: item.Name, Age: item.Age, Sex: item.Sex});
}
