pega todo o extrato do nubank para jogar num csv :)

nubank_extrato.js

var csv = ''
var columns = document.getElementsByClassName("charge");
for (var i = 0; i < columns.length; i++) {
    item = document.getElementsByClassName("charge").item(i);
    date = item.getElementsByClassName("date")[0].textContent;
    description = item.getElementsByClassName("description")[0].textContent;
    amount = item.getElementsByClassName("amount")[0].textContent;
    csv += date + ";" + description + ";" + amount.replace(",", ".") + ";\n";
}
console.log(csv)
