Changing strings of an object in a foreach

Question

I’m in trouble: I mount an object from an insert list:

This list I put in a variable and insert inside a function with foreach, however, so that it works correctly within the function can not have quotes (") in the records; The correct is to stay as follows:

Thus, with the quotes in each record, the final result does not have the data of the Array that is made the function of the foreach, but as written in the first image, it is printed as: ["Bairro: row.bairro"] because of the quotes. I need to make it look like in the second image.

Return of the Associated variable:

Function without being dynamic:

Function mounting the object:

List for dynamic choice of items:

From what I understand you want to mount a dynamic object with attributes that are marked with checked: true in your itemsList.

Your end result is getting "Neighborhood: Row.neighborhood" as you are including only strings in your array.

One solution I found would be to filter only the items that are with checked: true, and then iterate over your array associated creating new objects only with the attributes you want.

const itemsList = [
 {"id": 1, "name": "bairro", "checked": true, "row": "bairro", "title": "Bairro"},
 {"id": 2, "name": "celular", "checked": false, "row": "celular", "title": "Celular"},
 {"id": 3, "name": "cep", "checked": true, "row": "cep", "title": "Cep"},
];

const associated = [
  {"bairro": 'PARAISO', 'celular': "11111", 'cep': '29144-254'},
  {"bairro": 'OSASCO', 'celular': "22222", 'cep': '22455-774'},
];

// filtro apenas os itemsList que estão como true
const listRowsIterable = itemsList.filter(item => item.checked == true);

//monto objeto dinamicamente apenas com os atributos que quero 
const excel = associated.map(row => {
  let rowExcel = {};
  listRowsIterable.forEach(item => {
    //item.title - adiciona um atributo dinâmico no seu novo objeto
    //item.row - pega o valor que está no seu objeto associated dinâmicamente 
    rowExcel[item.title] = row[item.row];
  });
  return rowExcel;
});

console.log(excel);
