I need to convert JSON object string to a JavaScript array.

This my JSON object:

{"2013-01-21":1,"2013-01-22":7}

And I want to have:

var data = new google.visualization.DataTable();
data.addColumn('string', 'Topping');
data.addColumn('number', 'Slices');

data.addRows([
    ['2013-01-21', 1],
    ['2013-01-22', 7]
]);

How can I achieve this?

Cheating -> string.split(',') – adeneo Jan 25 at 18:53
@adeneo he wants array in array, with your method it will be just one array – salexch Jan 25 at 18:55

var json_data = {"2013-01-21":1,"2013-01-22":7};
var result = [];

for(var i in json_data)
    result.push([i, json_data [i]]);


var data = new google.visualization.DataTable();
data.addColumn('string', 'Topping');
data.addColumn('number', 'Slices');
data.addRows(result);

@user1960311 you welcome – salexch Jan 25 at 19:02
I would like something like this: 2013-01-21 ==> 1 2013-01-22 ==> 7 (like a hashtable) – user1960311 Jan 25 at 19:04
@user1960311 That's what you have now – Ian Jan 25 at 19:07
