Extract data from N°26 bank transactions page

N26transactions.js

let balance = 0;
let transactions = [];
for (elem of document.querySelectorAll('a[href^="/transactions"]')) {
 console.log(Array(20).join('-'));
 const parent = elem.parentNode;
 if (!parent) {
	 console.warn('skip [parent]', elem, elem.innerText);
	 continue;
 }
 const amountNode = parent.nextSibling;
 if (!amountNode) {
	 console.warn('skip [sibling]', elem, elem.innerText);
	 continue;
 }
 const amountText = amountNode.innerText;
 if (amountText.indexOf('My Account') !== -1) {
	 console.warn('skip [balance]', elem, elem.innerText);
	 continue;
 }
 const cleanAmountText = amountText
	.replace(/.*\r?\n?[^−]*(−?€\d+\.\d+).*/, '$1')
	.replace('−', '-')
	.replace('€', '');
 const amount = parseFloat(cleanAmountText);
 if (isNaN(amount)) {
	 console.warn('skip [NaN]', amountText, cleanAmountText, elem, elem.innerText);
	 continue;
 }
 const subject = elem.innerText;
 transactions.push( { subject: subject, amount: amount } );
 balance += amount;
}

console.log('TOTAL BALANCE: ' + balance);
console.log(JSON.stringify(transactions));

Suspect irregularities about your N°26 account balance? That's why I created this script.
Note that all data must be loaded before executing this script and the script uses floats for calculation so expect some minor difference to the actual amount. No warranty is provided.

Note that under downloads there is the possibility to export CSV and PDF, but these may not include the newest transactions.
