How to convert JSON Http response to Array in AngularJS 2 - arrays

Question

I'm doing a Http get in Angular 2 and the response is a JSON. However, i'm trying to use this in a ngFor but i can't because it isn't an Array.
How can I convert JSON to Array in Angular 2? I searched in many websites but didn't discover a effective way to do that.
Edit 1:
The response is like that:
{

Answer 1

I think if you want to pass from json to array you could do the following command:
var arr = []
for(i in json_object){
arr.push(i)
arr.push(json_object[i])
}
Then you have every keys in the even index and every contents in the odd index

Answer 2

Well, I really don't see the point here. Arrays are for operating with lists of similar objects or types, not for complex structures. If you had a bunch of objects similar to the one you show, then it would make sense. Anyways, if you really want an array then you could do it with recursion and create a flat array of the properties.
var flatPropertyArray = [];
function flatten(obj) {
for (var property in obj) {
if (obj.hasOwnProperty(property)) {
if (typeof obj[property] == "object")
flatten(obj[property]);
else
flatPropertyArray.push(property);
}
}
}
pass your JSON into the flatten func.
