I was having issues with stringify running out of memory and other solutions didnt seem to work  at least I couldn t get them to work  which is when I stumbled on this thread  Thanks to Rohit Kumar I just iterate through my very large JSON object to stop it from crashing  var j   MyObject  var myObjectStringify       MyObject       var last   j length var count   0  for  x in j        MyObjectStringify    JSON stringify j x        count        if  count  lt  last          MyObjectStringify           MyObjectStringify            MyObjectStringify  would give you your string representaion  just as mentioned other times in this thread  except if you have a large object  this should also work - just make sure you build it to fit your needs - I needed it to have a name than array

The existing JSON replacements where too much for me  so I wrote my own function  This seems to work  but I might have missed several edge cases  that don t occur in my project   And will probably not work for any pre-existing objects  only for self-made data   function simpleJSONstringify obj        var prop  str  val          isArray   obj instanceof Array       if  typeof obj      object   return false       str   isArray                   function quote str            if  typeof str      string   str   str toString            return str match               str         str replace    g                          for  prop in obj            if   isArray                   quote property             str    quote prop                                quote value         val   obj prop           str    typeof val      object    simpleJSONstringify val    quote val           str                        Remove last colon  close bracket     str   str substr 0  str length - 2       isArray                     return str

Check out updated better way by Thomas Frank    JSON stringify revisited      Update May 17  2008  Small sanitizer   added to the toObject-method  Now   toObject   will not eval   the string   if it finds any malicious code in   it For even more security  Don t set   the includeFunctions flag to true       Douglas Crockford  father of the JSON concept  wrote one of the first stringifiers for JavaScript  Later Steve Yen at Trim Path wrote a nice improved version which I have used for some time  It s my changes to Steve s version that I d like to share with you  Basically they stemmed from my wish to make the stringifier          handle and restore cyclical references     include the JavaScript code for functions methods  as an option      exclude object members from Object prototype if needed
