how to convert a json object into json array - json

Question

I am getting json from asana that is an object (data) of several objects. How do I make data an array?
{"data":{"id":5571422294129,"created_at":"2013-05-24T15:31:50.340Z","modified_at":"2013-05-24T15:32:21.260Z","name":"testProject","notes":"","archived":false,"workspace":{"id":5571305742112,"name":"TestITAT"},"followers":[{"id":5571289325327,"name":"John Doe"}]}}
I am trying to put this in a data table using aoColumns. If there is no need to convert "data" to an array please let me know how to use this JSON in datatables without it.

It is not that complicated. You can use DataTables aaData for this. I assume your JSON contains multiple "data":{..}, "data":{..}, "data":{..} ?
Then, consider this as test data :
var data = [
{"data":{"id":1571422294129,"created_at":"2010-05-24T15:31:50.340Z","modified_at":"2010-05-24T15:32:21.260Z","name":"testProject","notes":"","archived":false,"workspace":{"id":5571305742112,"name":"TestITAT"},"followers":[{"id":5571289325327,"name":"John Doe"}]}},
{"data":{"id":2571422294129,"created_at":"2011-05-24T15:31:50.340Z","modified_at":"2011-05-24T15:32:21.260Z","name":"Project A","notes":"","archived":false,"workspace":{"id":5571305742112,"name":"TestITAT"},"followers":[{"id":5571289325327,"name":"John Doe"}]}},
{"data":{"id":3571422294129,"created_at":"2012-05-24T15:31:50.340Z","modified_at":"2012-05-24T15:32:21.260Z","name":"Project B","notes":"bla bla","archived":false,"workspace":{"id":5571305742112,"name":"TestITAT"},"followers":[{"id":5571289325327,"name":"John Doe"}]}}
];
HTML markup
<table id="test">
<thead>
<tr>
<th>archived</th>
<th>created_at</th>
<th>id</th>
<th>modified_at</th>
<th>name</th>
<th>notes</th>
</tr>
</thead>
<tbody>
</tbody>
</table>
convert JSON to aaData-array :
var aaData = [];
for (var i=0;i<data.length;i++) {
aaData.push([
data[i].data.archived,
data[i].data.created_at,
data[i].data.id,
data[i].data.modified_at,
data[i].data.name,
data[i].data.notes
]);
}
Initialize the table
$('#test').dataTable({
"aaData": aaData
});
result :

I am not sure what you are exactly attempting to do, but...
If you are trying to deserialize the JSON into a data table you want something like this. This will take your JSON and deserialize it to an object, it won't exactly work with a data table but rather custom classes decorated with DataContract and DataMember attributes. But I think it may be a good starting point for you.
Public static T DeSerialize<T>(string strJSON)
{
T obj = Activator.CreateInstance<T>();
MemoryStream ms = new MemoryStream(Encoding.Unicode.GetBytes(strJSON));
DataContractJsonSerializer serializer = new DataContractJsonSerializer(obj.GetType());
obj = (T)serializer.ReadObject(ms);
ms.Close();
ms.Dispose();
return (obj);
}
Here is a very useful article regarding serializing JSON. HTH :)
