Чтобы превратить строковое представление в массив, нужно воспользоваться функцией eval():

eval("(" + json_string + ")");

А чтобы превратить массив в строковое представление:

/**
 * Converts the given data structure to a JSON string.
 * Argument: arr - The data structure that must be converted to JSON
 * Example: var json_string = array2json(['e', {pluribus: 'unum'}]);
 * 			var json = array2json({"success":"Sweet","failure":false,"empty_array":[],"numbers":[1,2,3],"info":{"name":"Binny","site":"http:\/\/www.openjs.com\/"}});
 * [url]http://www.openjs.com/scripts/data/json_encode.php[/url]

function array2json(arr) {
    var parts = [];
    var is_list = (Object.prototype.toString.apply(arr) === '[object Array]');

    for(var key in arr) {
    	var value = arr[key];
        if(typeof value == "object") { //Custom handling for arrays
            if(is_list) parts.push(array2json(value)); /* :RECURSION: */
            else parts[key] = array2json(value); /* :RECURSION: */
        } else {
            var str = "";
            if(!is_list) str = '"' + key + '":';

            //Custom handling for multiple data types
            if(typeof value == "number") str += value; //Numbers
            else if(value === false) str += 'false'; //The booleans
            else if(value === true) str += 'true';
            else str += '"' + value + '"'; //All other things
            // :TODO: Is there any more datatype we should be in the lookout for? (Functions?)

            parts.push(str);
        }
    }
    var json = parts.join(",");
    
    if(is_list) return '[' + json + ']';//Return numerical JSON
    return '{' + json + '}';//Return associative JSON
}

Пример:

var json_string = array2json(['e', {pluribus: 'unum'}]);//Returns '["e", {"pluribus": "unum"}]' 

var data = {
			"success":"Sweet",
			"failure":false,
			"empty_array":[],
			"numbers":[1,2,3],
			"info":{
				"name":"Binny",
				"site":"http:\/\/www.openjs.com\/"
			}
		};
var json = array2json(data); // Returns {"success":"Sweet","failure":false,"empty_array":[],"numbers":[1,2,3],"info":{"name":"Binny","site":"http:\/\/www.openjs.com\/"}}
