How to Parse nested Json In Java script

I have this json in js,
and i am trying to get the key from the "Data" Object, like the SessionId and Email.
Please Help...
{
"HasError": false,
"Errors": [],
"ObjectName": "WebCheckoutCreateSessionResponse",
"Data": {
"HasError": false,
"ReturnCode": 0,

}
},
"ResponseType": 0
}
const population = JSON.parse(xhr.responseText);
for (const key in population) {
if (population.hasOwnProperty(key)) {
console.log(`${key}: ${population[key]}`);
}
}

You forgot to index the Data property.
const population = JSON.parse(xhr.responseText).Data;
for (const key in population) {
console.log(`${key}: ${population[key]}`);
}

How to structure and all data in the objective from Json at App script

The JSON data I am working on it. This is coming from Facebook ad API. This is being build for google data studio connector
{
"data": [
{
"adcreatives": {
"data": [
{
"actor_id": "8834759718540",
"id": "538"
}
]
},
"insights": {
"data": [
{
"ad_id": "34536578578",
"impressions": "89108",
"actions": [
{
"action_type": "comment",
"value": "02"
},
{
"action_type": "post",
"value": "03"
}
],
"date_start": "2022-06-11",
"date_stop": "2022-07-10"
}
],
"paging": {
"cursors": {
"before": "MAZDZD",
"after": "MAZDZD"
}
}
},
"created_time": "2022-06-10T22:59:33+0600",
"id": "34536578578"
},
{
"adcreatives": {
"data": [
{
"actor_id": "7834759718970",
"id": "342"
}
]
},
"insights": {
"data": [
{
"ad_id": "238509545896206",
"impressions": "57803",
"actions": [
{
"action_type": "post_engagement",
"value": "2102"
},
{
"action_type": "page_engagement",
"value": "03"
}
],
"date_start": "2022-06-11",
"date_stop": "2022-07-10"
}
],
"paging": {
"cursors": {
"before": "MAZDZD",
"after": "MAZDZD"
}
}
},
"created_time": "2022-06-11T22:59:33+0600",
"id": "238509545896206"
}
],
"paging": {
"cursors": {
"before": "dfgdfgdfgdfsdgdfgdfgdfgdfgdgdg",
"after": "yuyuyuyutyuytuyutytynfrgersggsgs"
}
}
}
Here is the JavaScript code I have used in google app script but it is showing error. I know it is totally wrong
var data = {data: parseData.data.map(({actions, ...rest}) => ({...rest,...Object.fromEntries(actions.map(({action_type, value}) =>[action_type, value]))}))};
console.log(data);
Output should be like the following way so that I can get all the data in objective
{
"data": [
{
"actor_id": "8834759718540",
"id": "538",
"ad_id": "34536578578",
"impressions": "89108",
"comment": "02",
"post": "03",
"date_start": "2022-06-11",
"date_stop": "2022-07-10",
"created_time": "2022-06-10T22:59:33+0600"
},
{
"actor_id": "7834759718970",
"id": "342",
"ad_id": "238512373324806",
"impressions": "57803",
"post_engagement": "2102",
"page_engagement": "03",
"date_start": "2022-06-11",
"date_stop": "2022-07-10"
"created_time": "2022-06-11T22:59:33+0600"
}
],
"paging": {
"cursors": {
"before": "MAZDZD",
"after": "MQZDZD"
}
}
}

You can try the code below, but it only works if adcreatives.data and insights.data have only 1 element :
let part = data.data.map(item => ({
"actor_id": item.adcreatives.data.at(0).actor_id,
"id": item.adcreatives.data.at(0).id,
"ad_id": item.insights.data.at(0).ad_id,
"impressions": item.insights.data.at(0).impressions,
"comment": item.insights.data.at(0).actions.at(0).value,
"post": item.insights.data.at(0).actions.at(1).value,
"date_start": item.insights.data.at(0).date_start,
"date_stop": item.insights.data.at(0).date_stop,
"created_time": item.created_time
}));
let result = {
data: part,
paging: data.paging
}
console.log(result);

How to update a value in a complex fhirBundle JSON?

Given a bewildering fhir document like https://raw.githubusercontent.com/Notarise-gov-sg/api-notarise-healthcerts/master/test/fixtures/v2/pdt_art_with_nric_unwrapped.json
I need to update the part the JSON from { "id": "NRIC-FIN", "value": "S9098989Z" } to { "id": "NRIC-FIN", "value": "foobar" } and then emit the whole JSON again with that change.
I just about know how to access the value.
const fs = require("fs");
let rawdata = fs.readFileSync("pdt_art_with_nric_unwrapped.json");
let art = JSON.parse(rawdata);
let nric = art.fhirBundle.entry
.flatMap((entry) => entry.resource)
.find((entry) => entry.resourceType === "Patient")
.identifier.find((entry) => entry.id === "NRIC-FIN").value;
console.log(nric);
Though I am puzzled how to update this value since it's so difficult to access. Am I missing a trick? I don't want to use regex btw!

You seem to be very close - why not just set .value using the syntax you already have...?
const fs = require("fs");
let rawdata = fs.readFileSync("pdt_art_with_nric_unwrapped.json");
let art = JSON.parse(rawdata);
let nric = art.fhirBundle.entry
.flatMap((entry) => entry.resource)
.find((entry) => entry.resourceType === "Patient")
.identifier.find((entry) => entry.id === "NRIC-FIN").value = 'foobar';
console.dir(art.fhirBundle.entry)
... results in:

... clearly showing foobar set as you seem to desire. (Feel free to test with this Repl.it).
To "emit the full JSON" again you would just re-stringify it:
let fullJSON = JSON.stringify(art);

Instead of traversing the object manually you can use library like Jsonpath:
function replace() {
data = JSON.parse(data);
jsonpath.apply(data,
'$.fhirBundle.entry[?(#.resource.resourceType == "Patient")].resource.identifier[?(#.id == "NRIC-FIN")].value',
function(value) {
document.body.innerHTML += `value=${value}<br>`;
return 'foobar';
});
document.body.innerHTML += `updated JSON:<br> <pre>${JSON.stringify(data, undefined, 2)}</pre`;
}
let data =

If you are flat out replacing values without any other logic, and in case if you decide to use RegEx, then you can use String.replace().
let data =

"birthDate": "1990-01-15"
}
}`
let targetId = 'NRIC-FIN';
let find = new RegExp(`(?<=${targetId}.*value":\\s*").*?(?=")`, 'ig');
data = data.replace(find, 'foobar');;
document.write(`<pre>${data}</pre>`);
Note: In the regular expression, I have used i flag for case insensitive search. Used g flag to replace all occurrences of the id. If the id is unique and there is going to be only one occurrence in entire .json file then don't use g flag.

Get a value from Nested JSON

I am completely new to Node.js. I have to read specific value from a API responded Nested JSON. I have tried to figure out but getting Undefined instead of the value. Whenever I am trying to read the base object I am getting the responded value but whenever I am trying to read the object under array then I am getting Undefined value.
Code Snippet:
var https = require('https');
var optionget = {
host: 'api-dev.dataoverflow.com',
port: 443,
path: '/test1/test2/',
method: 'GET',
HEADERS: {
'Authorization': 'Basic grege==',
'X-PruAppID : '
PlainCardPortal '
}
};
console.info(optionsget)
var reqGet = htttps.request(optionsget, function(res) {
console.log("statusCode: ", res.statusCode);
res.on('data', function(d) {
process.stdout.write(d);
process.stdout.write(jsonobj);
var Value = jsonobj.items.item.topping.type;
console.log(Value)
});
});
reqGet.end();
reqGet.on('error', function(e) {
console.error(e);
});
var optionsgetmsg = {
host: 'api-dev.dataoverflow.com',

I want to read type : Glazed from this JSON only but I am getting Undefined.

You have to iterate over the values in an array. You cannot access them using . notation. Use map to iterate over the array and get they types in the topping array
var jsonobj = {
"items": {
"item": [{
"id": "0001",
"type": "donut",
"name": "Cake",
"ppu": 0.55,
"batters": {
"batter": [{
"id": "1001",
"type": "Regular"
},
{
"id": "1002",
"type": "Chocolate"
},
{
"id": "1003",
"type": "Blueberry"
},
{
"id": "1004",
"type": "Devil's Food"
}
]
},
"topping": [{
"id": "5001",
"type": "None"
},
{
"id": "5002",
"type": "Glazed"

{
"id": "5004",
"type": "Maple"
}
]
}
]
}
}
var Value = jsonobj.items.item.map(e=>e.topping)[0].map(x=>x.type);
console.log(...Value)

Javascript: Loop through nested objects and arrays

The way i go is the following. But i need a way to append the channels to each Consent. Is there a way to solve this?
consentsList.forEach((consent, index, array) => {
consent.consents.forEach((c) => {
Object.keys(c).forEach((key) => {
dd.content.push(
{
columns: [
{
text: `${key}: `, style: 'text'
},
{
text: c[key], style: 'text'
}
]
}
);
});
});
Consents.push(consent);
if (index !== array.length - 1) {
dd.content.push({
margin: [0, 0, 0, 5],
canvas: [{
type: 'line', x1: 0, y1: 5, x2: 595 - (2 * 40), y2: 5, lineWidth: 0.6
}]
});
}
});
I want to output the individual channels where channels is on the top of each entry

You can extract the titles using map. And concantanate them using join like this.
let value = "";
if(key === "channels"){
value = c[key].map(x => x.title).join(" ,");
}
else {
value = c[key];
}
columns: [
{
text: `${key}: `, style: 'text'
},
{
text: value, style: 'text'
}
]

I have written a piece of code, hope this is what you're looking for. It is not optimized, try to optimize at your will
var a = responseData;
a.forEach(function(items) {
var allChannels = [];
items.consents.forEach(function(innerItems){
innerItems.channels.forEach(function(value){
allChannels.push(value.title);
})
items.allChannels = allChannels.join();
})
});
console.log(a);
