How to parse multi-line JSON response to exact a particular key's value?

Question

I'm trying to parse a multi-line JSON response to get a value for a key using JavaScript. I read we can't parse multi-line json, how I can achieve getting "Created" value from below json?

I tried converting the JSON to string and used replace to converting multi-line to single line with \n as deliminator. -- Unable to replace multi-liner text.

I tried extracting index of mischief key value and remove from the string -- Syntax error.

var v1 =  {
    "data": {
        "type": "articles",
        "id": "1",
        "attributes": {
            "title": "JSON:API paints
my bikeshed!",
            "body": "The shortest article. Ever.",
            "created": "2015-05-22T14:56:29.000Z",
            "updated": "2015-05-22T14:56:28.000Z"
        },
        "relationships": {
            "author": {
                "data": {
                    "id": "42",
                    "type": "people"
                }
            }
        }
    }
};
alert(result.data.attributes.created);

My expectation is to get 2015-05-22T14:56:29.000Z as output.

In your example i see syntax error

Try to change string definition "" to ``

var v1 =  {
    "data": {
        "type": "articles",
        "id": "1",
        "attributes": {
            "title": `JSON:API paints
my bikeshed!`,
            "body": "The shortest article. Ever.",
            "created": "2015-05-22T14:56:29.000Z",
            "updated": "2015-05-22T14:56:28.000Z"
        },
        "relationships": {
            "author": {
                "data": {
                    "id": "42",
                    "type": "people"
                }
            }
        }
    }
};

console.log(v1.data.attributes.created)

In case of new line you can replace all the new lines and then parse the JSON.
Each OS generate different newline characters you need to be aware of that while replacing newline characters.

var v1 =  `{
    "data": {
        "type": "articles",
        "id": "1",
        "attributes": {
            "title": "JSON:API paints
my bikeshed!",
            "body": "The shortest article. Ever.",
            "created": "2015-05-22T14:56:29.000Z",
            "updated": "2015-05-22T14:56:28.000Z"
        },
        "relationships": {
            "author": {
                "data": {
                    "id": "42",
                    "type": "people"
                }
            }
        }
    }
}`;

var result = v1.replace(/(?:\r\n|\r|\n)/g, '');

var resultObj = JSON.parse(result);

console.log(resultObj.data.attributes.created);
