Whats the cleanest way to repair this JSON object string in javascript?

Question

I am doing some site crawling, and right now, I find this string of a JSON object

{ "results" : [

    {
        id: 775664,
        status: "In-Stock",
        ffmtCenterId: '10601',
        altText: "In-Stock",
        qty: 6
    }

]}

and I wan't to convert that to a object using JSON.parse() but this doesn't work because there are syntax errors, like you need quotes around the key values. I tried eval() but it didn't work.

Does anyone know whats a good way to fix this string so that I can convert it into an object?

Thanks

Answer 1

how did you try eval() ?

eval("var a = " + incoming_string);
var fixed = JSON.stringify(a);

a is the object, I don't think you need that fixed string.

Of course, eval an unknown string is not safe.

Answer 2

The hjson project seems to be a possible solution. Thier online converter managed to parse your broken structure into proper JSON though there seem to be some quirks in the conversion.

Answer 3

Though I see you've commented that you've already found a fix, here's a double replace() that worked on this sample as a multiline string:

var a = `{ "results" : [

    {
        id: 775664,
        status: "In-Stock",
        ffmtCenterId: '10601',
        altText: "In-Stock",
        qty: 6
    }

]}`

var b = a.replace(/(\w+)(: )/g, "\"$1\" $2" ).replace(/(:\s+)['](\w+)['](,\n)/g, "$1\"$2\"$3" )

var jo = JSON.parse( b )

Without the 2nd replace() , I was getting JSON.parse errors in Firebug on the ffmtCenterId data.
