Use JSON.parse() to check it. Try:

try
{
   var json = JSON.parse(your string);
}
catch(e)
{
   //not a json
}

Fiddle here.

add this function to your code:

function isJSON(data) {
    try {
        JSON.parse(data);
        return true;
    } catch (ex) {
        return false;
    }
}

and simply to use it :

if(isJSON(data))
    // it's json, do whatever you want
else
    // it's not json, do whatever you want
