The initial line is the only place where JSON headers are displayed

Currently diving into the world of JavaScript and tackling a project head-on. However, I've hit a roadblock as the JSON file I'm working with looks different from what I'm used to. Can anyone assist me in figuring out how to display this data in my HTML file?

{
  "values": [
    [
      “name”,
      “age”,
      “location”
    ],
    [
      “Alice”,
      “28”,
      “Florida.”
    ]
]
}

I'm accustomed to working with this format

[name:"Alice",age:"28",location:"Florida"]
[name:"Bob",age:"27",location:"Texas"]

Is there a way to transform it to match that style?

Appreciate any help!

Answer №1

Alright, so without those strange quotes, it's pretty straightforward

const dataValues = {values: [["name","age","location"],["Alice","28","Florida."]]};

const [labels, ...info] = dataValues.values

const finalResult = info.map(info => Object.fromEntries(labels.map((label, index) => [label, info[index]])));

console.log(finalResult);

Or

Doing it like a pro...

const dataValues = {values: [["name","age","location"],["Alice","28","Florida."]]};

const {values: [labels, ...details]} = dataValues;

const finalResult = details.map(info => Object.fromEntries(labels.map((label, index) => [label, info[index]])));

console.log(finalResult);

Answer №2

You are provided with a 2-dimensional array, in which the first array consists of keys and the second array contains values.

Utilize the function below to convert this into the desired output.

const arr = [["name","age","location"],["Alice","28","Florida."]];

function arrToObject (arr){
    //assuming header
    var keys = arr[0];
    //extract keys from the main array
    var newArr = arr.slice(1, arr.length);

    var formatted = [],
    data = newArr,
    cols = keys,
    l = cols.length;
    for (var i=0; i<data.length; i++) {
            var d = data[i],
                    o = {};
            for (var j=0; j<l; j++)
                    o[cols[j]] = d[j];
            formatted.push(o);
    }
    return formatted;
}

console.log(arrToObject(arr));

By the way, this function was discovered from this source
