I have a json file with contents like this:
{
\"aaa\":{
\"status\":\"available\",
\"classkey\":\"dotnet\"
},
\"bbb\":{
Never used JSON, but according to http://labs.adobe.com/technologies/spry/samples/data_region/JSONDataSetSample.html#Example1 , it's possible to create an ordered array. Just remove the key and colon in your key-value pairs. (Someone please tell me whether this works - it may be dependent on values being defined in all objects, or it may allow null columns).
