how to make an array from nested json

Question

The JSON data I am working on it. This is coming from Facebook ad API. This is being build for google data studio connector

Here is the JavaScript code I have used in google app script but it is showing error. I know it is totally wrong

 const parseData = { "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" } } }; 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"
    }
  ],
 
}

Not sure how you suppose to handle the nested arrays, but for particular data this code does the job:

 const parseData = { "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" } } }; var new_data = []; for (let obj of parseData.data) { var new_obj = {}; new_obj.actor_id = obj.adcreatives.data[0].actor_id; new_obj.id = obj.adcreatives.data[0].id; new_obj.ad_id = obj.insights.data[0].ad_id; new_obj.impressions = obj.insights.data[0].impressions; var actions = obj.insights.data[0].actions; actions.forEach(a => new_obj[a.action_type] = a.value) new_obj.date_start = obj.insights.data[0].date_start; new_obj.date_stop = obj.insights.data[0].date_stop; new_obj.created_time = obj.created_time; new_data.push(new_obj) } console.log(new_data);
