Convert object of array to object

Question

I have this

[
{"2015":11259750.05},
{"2016":14129456.9}
]

and I want to convert this to

[
[2015,11259750.05],
[2016,14129456.9]
]

is there any function using javascript we can do this.

just to conclude I have a header as well which I want to include with the above result,

[
    {"label":"SecuredYear","type":"string"},
    {"label":"ValueInDh‌s","type":"number"}
]

along with above then it should look like `

[[
  {"label":"SecuredYear","type":"string"},
  {"label":"ValueInD‌hs","type":"number"}‌
], [2015,11259750.05],[2016,14129456.9]
]`

thanks

do you realize the end result you are asking for in a array of array (multidimentional array) and not a object as you mentioned in the Title — Rajshekar Reddy

Use Array#map method with Object.keys method to generate the array and later add original array at beginning using Array#unshift method.

var data = [{
  "2015": 11259750.05
}, {
  "2016": 14129456.9
}];

// iterate over the array to generate new array
var res = data.map(function(v) {
  // get the property name from object
  var k = Object.keys(v)[0];
  // generate element of the array
  return [k, v[k]];
  // if you want to convert property name to number then
  // return [+k, v[k]];
});

// add the original array at beginning
res.unshift(data);

console.log(res);

You could iterate the given array, take the key form the object, make a new array with the data and later unshift the header to the result.

var header = [{ label: "SecuredYear", type: "string" }, { label: "ValueInDh‌s", type: "number" }],
    data = [{ "2015": 11259750.05 }, { "2016": 14129456.9 }],
    result = data.map(function (o) {
        var k = Object.keys(o)[0];
        return [+k, o[k]];
    });

result.unshift(header);

console.log(result);

.as-console-wrapper { max-height: 100% !important; top: 0; }

You can loop your array and then extract each object key Object.keys(obj)[0] and its value obj[key] as shown below.

use parseint() to convert your string data (in your case the object key) into a integer

var data = [{
  "2015": 11259750.05
}, {
  "2016": 14129456.9
}];

var newData = [];

data.forEach(function(obj,index){
   var key= Object.keys(obj)[0];
   newData.push([parseInt(key,10),obj[key]]);
});

console.log(newData);

var data =[{"2015":11259750.05},{"2016":14129456.9}]
var res=[];

  data.map(function(a){
  Object.keys(a).forEach(function(b){
    res.push([parseInt(b),a[b]])
    })
                
    })
  console.log(res)

Try this it is working as per your expectation :

var jsonObj = [
{"2015":11259750.05},
{"2016":14129456.9}
];

var newArr = [];
for (var i in jsonObj) {
  var objKeys = Object.keys(jsonObj[i]);
  newArr.push(Object.keys(jsonObj[i]));
  newArr[i].push(jsonObj[i][objKeys[0]]);
}

console.log(newArr);
