格式化JSON对象，从单引号到双引号

Question

I'm using a data-set given to me and I'm trying to parse (Using Node) the JSON objects returned to me,

Turns out they are all using single quotations, and from my research JSON uses double.

Example of a JSON object I get returned!

{
    'cast_id': 16,
    'character': 'Alexander Haig',
    'credit_id': '52fe43c59251416c7501d72d',
    'gender': 2,
    'id': 6280,
    'name': 'Powers Boothe',
    'order': 2,
    'profile_path': '/3nNL6AvMAYq0BmHKM79RnRZVq3i.jpg'
},

I've been using str.replace() to sort the objects out before JSON.parse() which was fine untill I found objects like this one

{
    'cast_id': 26,
    'character': '"Jack Jones"',
    'credit_id': '52fe43c59251416c7501d751',
    'gender': 2,
    'id': 6840,
    'name': 'Larry Hagman',
    'order': 16,
    'profile_path': '/40PVsGp5Wp5kbUhAefLHqjqbarc.jpg'
},

Notice the 'character': '"Jack Jones"', This has been causing me all types of issues!

I there a library that will help parse this all for me?

Am I missing something?

FYI:

I can't access each record as the JSON objects aren't stored separately instead, as a long string including up to 60 JSON objects.

I currently have a function that helps parse the data:

function formatJSON(cast) {
    cast = cast.replace(/(\w) "(\w)/g, "$1 *$2");
    cast = cast.replace(/(\w)" /g, "$1* ");         
    cast = cast.replace(/': '/g, '": "');
    cast = cast.replace(/', '/g, '", "' );
    cast = cast.replace(/'},/g, '"},');
    cast = cast.replace(/': /g, '": ');
    cast = cast.replace(/, '/g, ', "');
    cast = cast.replace(/{'/g, '{"');
    cast = cast.replace(/: None}/g, ': "None"}');
    cast = cast.replace(/'}/g, '"}');
    return cast;
}

Update

The data reportedly extracts nicely in python as a dictionary using ast.literal_eval()

By default, you don't need to replace a string which is wrapped by double quotes with the same string contains single quote. There is no difference between 'Jack Jones' and "Jack Jones" since all of them are string .

In your case, you're trying to replace something like this example:

 var str = '\\'Jack Jones\\''.replace(/'/g, '"'); console.log('\\'' + str + '\\'');

So, if you want to wrap all of properties names and values by double quotes, you can use JSON.stringify and JSON.parse like this:

 var cast = { 'cast_id': 16, 'character': 'Alexander Haig', 'credit_id': '52fe43c59251416c7501d72d', 'gender': 2, 'id': 6280, 'name': 'Powers Boothe', 'order': 2, 'profile_path': '/3nNL6AvMAYq0BmHKM79RnRZVq3i.jpg' }; cast = JSON.stringify(cast); cast = JSON.parse(cast); console.log(cast);
