Rename unknow key from json array in javascript

Question

I been searching with no success, i would like to iterate over a json object but this have diferent names on keys, below my code

  [{
    "05115156165165" :{
        "name":"John",
        "Phone":"515555"
    },
    "111111111":{
        "name":"John",
        "Phone":"515555"
    }
  }]

So basically i need in the following way:

    [{
    "data" :{
        "name":"John",
        "Phone":"515555"
    },
    "data":{
        "name":"John",
        "Phone":"515555"
    }
  }]

looks like you wrapped all the objects within an object, afaik - cannot have same key ("data"). — iAmOren

Just noticed, you need to have different key for each sub object otherwise last one will overwrite older one. — Hassan Imam

@fedesc, {a:1,a:2,a:3}=={a:3} = the 2 and 3 "disappear". If you look closely, you'll see that the expected is one object... — iAmOren

That's neither a "json array" nor a "json object" (There's no such thing as a "JSON Object"). That's an array with one object — Andreas

@iAmOren I did checked again that's why i removed my comment haha didn't notice the extra {} — fedesc

You can use Object.values to retrieve values for unknwon keys and reduce to transform input array:

let input = [{
"05115156165165" :{
    "name":"John",
    "Phone":"515555"
},
"111111111":{
    "name":"John",
    "Phone":"5155557"
}
}];

let result = input.reduce((acc,cur)=> {
   Object.values(cur).forEach(
      obj => {acc.push({ data: obj });}
   )
   return acc;
},[]);

console.log(result);

The key is use Object.entries to iterate through all the keys in the object, which in this case it has only 1 that the name is unknown in every object.

const data = [{
  "05115156165165": {
    "name": "John1",
    "Phone": "1111111"
  },
  "111111111": {
    "name": "John2",
    "Phone": "2222222"
  }
}]
let result = []
data.forEach(d => {
  for (const [key, value] of Object.entries(d)) {
    result.push({
      data: {
        name: value.name,
        Phone: value.Phone
      }
    })
  }
})
console.log(result)

You can do something like this:

let data = [{
  "05115156165165": {
    "name": "John1",
    "Phone": "1111111"
  },
  "111111111": {
    "name": "John2",
    "Phone": "2222222"
  }
}]
let result = []
data.forEach(d => {
  Object.keys(d).forEach(el => {
    result.push({
      data: d[el]
    })
  })
})
console.log(result)
