Returned AJAX string to an array

This is what I have. I have an AJAX call that returns a string (data.d) like this:

{"id": "03100500", "name": "Book I"},{"id": "03100507", "name": "Book I - ALT"},{"id": "03100505", "name": "Book I - M"},{"id": "03100600", "name": "Book II"}

I've tried:

var books = JSON.parse(data.d);

Basically getting an error "Uncaught SyntaxError: Unexpected token , in JSON"

End result i'd like:

var newArray = [{"id": "03100500", "name": "Book I"},{"id": "03100507", "name": "Book I - ALT"},{"id": "03100505", "name": "Book I - M"},{"id": "03100600", "name": "Book II"}]

Not even sure if it's possible

I think the missing [ was a copy and paste mistake. Assuming that, you are probably calling JSON.parse on an object. See image below:

Without the array delimiters, the string isn't valid JSON. Given the string without array delimiters, you can just add them before parsing:

let s = `{"id": "03100500", "name": "Book I"},{"id": "03100507", "name": "Book I - ALT"},{"id": "03100505", "name": "Book I - M"},{"id": "03100600", "name": "Book II"}`

// make new string with `[]` delimiters:
let o = JSON.parse('[' + s + ']')
console.log(o)

If the value is going to be flawed in more complicated ways like undelimited nested arrays, it will be harder and probably worth fixing it on the server if possible.
