How to convert a nested object into an array of objects?

Question

inputJson = {
 "mn": {
 "mt1": 1,
 "mtop": 2,
 "ot1": 3
 },
 "ln": {
 "mt1": 4,
 "mtop": 5,
 "ot1": 6
 }
}
OutputArrayOfJson=[
 { rs: "mt1", mn: 1, ln: 4 },
 { rs: "mtop", mn: 2, ln: 5 },
 { rs: "ot1", mn: 3, ln: 6 }
]

• rs is hardcode Key.

I don't know why am having hard time doing this operation.

• Felix Kling: What you have is not JSON. JSON is a language-independent, textual data format, just like XML or CSV. You simply have a JavaScript object and want to convert it to an array.

Answer 1

It is a conversion of javascript objects

inputJson = {
 "mn": {
 "mt1": 1,
 "mtop": 2,
 "ot1": 3
 },
 "ln": {
 "mt1": 4,
 "mtop": 5,
 "ot1": 6
 }
}
d = {};
for(var key1 in inputJson){ 
 for(var key2 in inputJson[key1]) { 
 if(!(key2 in d)){ 
 d[key2]={};
 } 
 d[key2][key1] = inputJson[key1][key2];
 }
}
v = []; 
for(var k in d){ 
 var o = {}; 
 o.rs=k; 
 for(var k2 in d[k]){ 
 o[k2] = d[k][k2]; 
 } 
 v.push(o);
}
//result is in v

note: the next time you should shown example code or not will help

Answer 2

You can iterate through the object and push each root property inside an array:

var arr = [];
for (var p in inputJson){
 arr.push(inputJson[p]);
}
console.log(arr);
