We can first entries of that object and then map it accordingly after that we convert that object using Object.fromentries. Here is an implementation:

const obj = {  "fullName": "abc", "age": 19 };

const result = Object.fromEntries(Object.entries(obj).map(([k,value])=>[k,{value, type:typeof value}]));

console.log({variable:result});

You can use Object.entries with .reduce()

let data = {
   "fullName": "abc",
   "age": 19,
}

let result = Object.entries(data).reduce((a, [key, value]) => {
   a.variables[key] = { value, type: typeof value}
   return a;
}, { variables: {}})

console.log(result);

Are you looking for JSON.parse to get a struct from your file, then JSON.stringify to create a json from your struct ?
