Parse Complex Json String

Question

I'm attempting to parse the following JSON string (not in control of the format, I know it's hideous).

    var json = '{"what.1.does":"anything", "nestedjsonstr":"{\"whatup\":\"nada\"}"}';
    obj = JSON.parse(json);

I'm getting Error: Unexpected token w in JSON at position 43 which is where the first value of nestedjsonstr begins. Is there any elegant way to parse this?

Maybe this can help you out. You replace the curly braces inside your string without the ", and remove the \.

var json = '{"what.1.does":"anything", "nestedjsonstr":"{\"whatup\":\"nada\"}"}';

json = json.replace('\"{', '{').replace('}\"', '}').replace('\\"', '"');

obj = JSON.parse(json);
console.log(obj);

Thanks. This works. Is it safe enough to clear all the escape characters though (as that would clear it in the entire json string)?

Maybe try json = json.replace('\"{', '{').replace('}\"', '}').replace('\\"', '"'). I'll edit the answer
