You can use jQuery.parseJSON

Live Demo

jsonobj = $.parseJSON('{"RetVal":"Ok","ValueRsp":[{"Feedback_Id":"22","Customer_Id":"543","Feedback_Type_Id":"1","First_Name":"Tester Tester","Last_Name":"NA","Nick_Name":"Xgcfyxfu"}]}');
alert(jsonobj.RetVal);
alert("jsonobj.ValueRsp[0].Customer_Id: " + jsonobj.ValueRsp[0].Customer_Id);

you can use the function:

var json_obj = JSON.parse("correct_json_format_string");

now you can use the json_object ot access all the properties:

var return_value = json_obj.RetVal;

Hope that helps.

a little bit of googling would have done it... 

var obj = JSON.parse(yourString);
// now use obj.RetVal
