You can try this:

JSON.stringify(
  Object.entries({"id" : 1, "name": "John"}).map(([key, value]) => ({
    key: key, 
    value: value
  }))
)

You can get the keys of obj using Object.keys() and map them to objects.

const obj = {
    "id": 1,
    "name": "John"
};
const result = Object.keys(obj).map(k => ({
    key: k,
    value: obj[k]
}));

console.log(result);
