JSON weird format access data

This is a JSON snip that is created in WooCommerce by a plugin that adds some metadata. I cannot change the formatting of this JSON because it is generated by a plugin. The problem is that the keys and the values are added in a weird way. I am iterating through the line_items and statically referencing this data which I don't want to do, I would like to know if there is a smart way to reference for example:
"key": "_cpo_product_id",
"value": "3572",
if this was formatted correctly it would be: "_cpo_product_id": "3572" and not have "value" as a key, and it would be accessed by: foo.line_items[i]._cpo_product_id
but with this configuration I am a bit lost, I am sure there is an easy way to find the value for a specific key. I am doing this on Google app scripts, but a solution in JavaScript should suffice.
JSON snip:
"line_items": [
{
"id": 749,
"name": "Dune",
"product_id": 3572,
"variation_id": 0,
"quantity": 1,
"tax_class": "",

{
"id": 24,
"total": "31.403148",
"subtotal": "31.403148"
}
],
"meta_data": [
{
"id": 11919,
"key": "_cpo_product_id",
"value": "3572",

},
{

How to make JavaScript object from the given json string

I have a large json data that I have to parse and get object out of the following Json string. I added just top part of that large json data. I tried to parse it by
let obj = JSON.parse(this.state.data);
it doesn't work, it breaks with this msg "SyntaxError: Unexpected token L in JSON at position 0".
If I get the console.log by console.log(JSON.stringify(this.state.data, null, 2)); and try to validate output by online JSON validator, it says it is valid JSON data. Could you please tell me how can I parse it?
{
"content": [
{
"_id": 1,
"name": "Warehouse A",
"location": {
"lat": 47.13111,
"long": -61.54801
},
"cars": {
"location": "West wing",
"vehicles": [
{
"model": "GX",
"price": 27395.26,
"licensed": false,
"_id": 15,
"make": "Lexus",
"year_model": 2005,
"date_added": "2017-11-12T00:00:00.000+00:00"
},
{
"model": "Q",
"price": 6103.4,
"licensed": false,
"_id": 9,
"make": "Infiniti",
"year_model": 1995,
"date_added": "2017-11-13T00:00:00.000+00:00"
},
.........xxxxxx continue

Your variable this.state.data is not a JSON. It's a Javascript Object, just like JSON, So, Why not just use let obj = this.state.data;

serialize javascript array of object with nested arrays

Good day! Could anyone suggest please, is it possible to serialize/unserialize array of object in JavaScript and do not lose nested arrays? I want to save it into the database but when I unserialize json I lose prices array.
I use JSON.stringify and JSON.parse.
const arr = [{
"HotSpotData": "<SchematicsDefinition><Schema2D><Rectangles><RectangleDefinition ZOrder=\"0\" Top=\"440\" Left=\"176\" Width=\"27\" Height=\"27\" ShapeType=\"2\"/></Rectangles></Schema2D></SchematicsDefinition>",

console.log(JSON.parse(JSON.stringify(arr)))

Json parse javascript : String displayed as NAN [duplicate]

This question already has answers here:
Unable to access JSON property with "-" dash [duplicate]

Closed 5 years ago.
So i am trying parse a json file. I am using alert to get the value of a particular field but whenever i pass this particular string it is displayed as nan
myjsondata=JSON.parse(json);
alert(myjsondata.result.parameters.College-name);
Json file
`{
"id": "1",
"timestamp": "2017-05-11T04:03:26.008Z",
"lang": "en",
"result": {
"source": "agent",

"intentName": "Default Welcome Intent"
},
"fulfillment": {
"speech": "Hi welcome from webfocus Api Ai",
"messages": [
{
"type": 0,
"speech": "Hi welcome from webfocus Api Ai"
},
{
"type": 0,
"speech": ""
}
]
},

"code": 200,
"errorType": "success"
},
"sessionId": "04737548-a3ff-485d-af1a-304edfee9486"
}`
alert with action and other fields are working fine . But for college it is displayed as NAN

You are getting a null value because parameters does not have a key called College-name:
"parameters": {},
Also, you might want to change your selection be using:
alert(myjsondata.result.parameters['College-name']);

How to get response from an API that returns same values with different answers? [duplicate]

This question already has answers here:
How can I access and process nested objects, arrays, or JSON?
(31 answers)
Closed 6 years ago.
(Sorry if the title doesn't make much sense, I couldn't figure out how to word it correctly)
So I'm trying to get the response from an API, but the API returns multiple responses with the same name.
Ex of a response:
{
"xuid": 2535436668322645,
"state": "Online",
"devices": [
{
"type": "XboxOne",
"titles": [
{
"id": 714681658,
"name": "Home",
"placement": "Background",
"state": "Active",
"lastModified": "2016-11-22T23:45:08.8296994Z"
},
{
"id": 74304278,
"activity": {
"richPresence": "Lvl 30 in Hudson Yards"
},
"name": "Tom Clancy's The Division",
"placement": "Full",
"state": "Active",
"lastModified": "2016-11-22T23:45:08.8296994Z"
}
]
}
]
}
So I was wondering, how would I be able to get the ID from the "second" response using JavaScript? (The one that says "Tom Clancy's The Division" in the name part) Thanks!

This should get you on the right track (untested)
var obj = jQuery.parseJSON(YOUR_JSON);
obj->devices[0]->titles[1]->id // second id
