I have following array of objects :

[
  {
    "userId": 1,
    "id": 1,
    "title": "delectus aut",
    "completed": false
  },
  {
    "userId": 1,
    "id": 2,
    "title": "quis ut",
    "completed": false
  }
]

I want following as output :

userId | id | title       | completed |
  1    | 1  | delectus aut| false     |
  1    | 2  | quis ut     | false     |

I have tried following using lodash , but somehow I feel there us better solution than this, considering the number of loops:

jsonObject = response; // consider the above mention object here.  
keys = _.keys(json[0]); 

Here what I found is that json[0] will not in all case going to be same, so what is the best way to find the solution for this.

Any help will be appreciated!!!

You can also do this in a quite simple way with ES6 and no lodash with Array.reduce:

let data = [{ "userId": 1, "id": 1, "title": "delectus aut", "completed": false }, { "userId": 1, "id": 2, "title": "quis ut", "completed": false } ]

let result = data.reduce((acc,cur) => 
   acc.push(Object.values(cur)) && acc, [Object.keys(data[0])])

console.log(result)

This question already has answers here: Convert json data to a� I am doing some data analysis in python, putting the results in form of a matrix stored into a numpy array. I would like to put this results into a report and the best way would be to put a table with a tabular inside containing the data.

Inspired from @Akrion's solution, here is the modified version. Little lengthy solution, but this will help you if:

  1. You have different keys in your JSON data
  2. You have different key sequence in the object
  3. Want to set a default value in case data is not available

const json = [
  {
    "userId": 1,
    "id": 1,
    "title": "delectus aut",
    "completed": true
  },
  {
    "completed": false,
    "userId": 1,
    "title": "quis ut",
    "id": 2,
    "extraProp": "test"
  },
];

const headers = Array.from(new Set(json.reduce((acc, cur) =>
  [...acc, ...Object.keys(cur)], [])));

const data = [headers];
const defaultValue = 'NA';

json.forEach(item => {
  data.push(headers.reduce((acc, header) =>
    acc.push(item.hasOwnProperty(header) ? item[header] : defaultValue) && acc, []));
});
console.log(data);

And you can now access each item in the new object using the conventional dot notation method (foo.bar). In the next section, we'll show you how to manually loop over an array to construct a new object. 2. Loop Over Array & Construct a New

First get the header of the table :

let firstObject = array[0];
let header = Object.keys(firstObject);

Now, you have keys in header object.

Use map or forEach on the array and store that in the variable.

let tableValues = table.map((a, i)=>{
    let row = []
    header.forEach((e)=>{row.push(a[e])});
return row;
});

Now you have header and tableValues

header is an array and tableValues is Array of Array

Convert JSON Data Dynamically to HTML Table using JavaScript, JSON or JavaScript Object Notation, as you know is a simple easy to understand data format. Here, in this article I'll show you how to convert JSON data to an HTML table dynamically The JSON for this example looks like this. The above JSON has an array of three different Books with its ID, Name, the Category it� The data object is the previous value of the reducer, and element is the current form element in the array. We then add a new property to the object using the element’s name property — this is the input’s name attribute in the HTML — and store its value there.

Since you want certain columns in a certain order, you should define an array of keys, and the use _.map() and _.pick() to get the values in the correct order from the object. Afterwards, concat the array of values to the array of keys:

const { flow, partialRight: pr, map, at, partial, concat, join } = _

const fn = keys => flow(
  pr(map, o => at(o, keys)),
  partial(concat, [keys]),
)

const keys = ['userId', 'id', 'title', 'completed']

const data = [{"userId":1,"id":1,"title":"delectus aut","completed":false},{"userId":1,"id":2,"title":"quis ut","completed":false}]

const result = fn(keys)(data)

console.log(result)
