transform a JSON object into a new format

Question

transform a JSON object into a new format

I am working with a JSON object that looks like this:

 [
  {
    "AF28110": 33456.75,
    "AF27989": 13297.26
  }
]

My goal is to convert it into the following format:

[ 
 { "name": "AF28110", "price": 33456.75},
 { "name": "AF27989", "price": 13297.26}
]

I have attempted to use various methods like .map() to achieve this transformation, but I have been unsuccessful so far.

If anyone has any insights or ideas on how to accomplish this task, your help would be greatly appreciated! Thank you.

Answer №1

Give this code a shot:

const result = [];
inputs.forEach(item => Object.keys(item).forEach(key => result.push({property: key, value: item[key]})))

Object.keys extracts the keys from each object, allowing you to create a separate array item for each property.

Utilizing the map method:

const items = [
  {
    "XV37293": 54982.16,
    "DN93842": 20371.43
  }
]

const result = Object.keys(items[0]).map(item => {
  return { product: item, price: items[0][item] };
});

console.log(result)

});

One way to achieve this is by utilizing concat, Object.keys, and map. By iterating through each item in the array, extracting keys from the object, and mapping each key to the desired name/price object, you can create a new array with the transformed data. Finally, flatten the resulting array using concat for a clean output.

For example:

const arr = [{
  "AF28110": 33456.75,
  "AF27989": 13297.26
}]

const result = [].concat(...arr.map(o => Object.keys(o).map(k => ({name: k, price: o[k]})))
console.log(result);

If you have a collection of various items in an array, the reduce method comes in handy.

let arr = [
  {"item1": 23.50,"item2": 10.75},
  {"item3": 35.20,"item4": 15.60}
];

let result = arr.reduce((collection, value) => collection.concat(Object.entries(value).map(obj => {return {name: obj[0], price: obj[1]}})), []);

console.log(result);

Give this a shot,

let data = '[{"AF28110": 33456.75,"AF27989": 13297.26}]';
let jsonData = JSON.parse(data);
let finalResult = [];
for (x = 0; x < jsonData.length; x++) {
 let properties = Object.keys(jsonData[x]);
 for (y = 0; y < properties.length; y++){
    finalResult[y] = '{ "name":' +properties[y] + ', "price":' + jsonData[x][properties[y]]+'}';
 } 
}
console.log(finalResult);

Many thanks.

Effective methods for achieving the desired outcome:

Utilizing the Object.keys function :

var data = [
  {
    "AF28110": 33456.75,
    "AF27989": 13297.26
  }
];

var result = Object.keys(data[0]).map(key => {
  return {"name": key, "value": data[0][key] };
});

console.log(result);

Using the Object.getOwnPropertyNames approach :

var data = [
  {
    "AF28110": 33456.75,
    "AF27989": 13297.26
  }
];

var result = Object.getOwnPropertyNames(data[0]).map(key => {
  return {"name": key, "value": data[0][key] };
});

console.log(result);
