I am getting a string value "/Date(1342709595000)/"in the JSON. I am trying to extract the digits alone and convert the epoch date to meaning ful Javascript Date in the format mm/dd/yy hh:mm:ss . I was able to achieve the first part of the question extracting the digits but couldnot convert it to date object human readable format as available in http://www.epochconverter.com/

There is nothing you really need to do, they are already milliseconds since epoch and javascript dates take milliseconds since epoch.
