how to json.stringify() a string

Question

i have a complex object which is stored as a string in a text file

This is my data which i am reading from a text file

 [
 {
    name: "V",
    number: 20,
    coords: {
        "cn": { 
            points: [
                [23,32,32],
                [32,32,32]
            ], 
            B: "VC", 
            label: "ds"
        }
    }
}]

I want to convert this to a JSON string

Note:- I cant use eval function I have tried this JSON.stringify but i am getting this output:-

"   [\r\n     {\r\n        name: \"V\",\r\n        number: 20,\r\n        coords: {\r\n            \"cn\": { \r\n                points: [\r\n                    [23,32,32],\r\n                    [32,32,32]\r\n                ], \r\n                B: \"VC\", \r\n                label: \"ds\"\r\n            }\r\n        }\r\n    }]"

You can use combination of eval() and JSON.stringify(). eval() will convert it into valid JavaScript object and now you can use JSON.stringify() to convert it into JSON string.

var str='[\
 {\
    name: "V",\
    number: 20,\
    coords: {\
        "cn": { \
            points: [\
                [23,32,32],\
                [32,32,32]\
            ], \
            B: "VC", \
            label: "ds"\
        }\
    }\
}]';

document.write(JSON.stringify(eval(str)));
