Code to copy
(function () {
function num(t) { return parseFloat((t || '').replace(/[^0-9.,]/g, '').replace(',', '.')) || 0; }
function scan() {
var rows = document.querySelectorAll('[role="row"]');
rows.forEach(function (r) {
var cells = r.querySelectorAll('[role="cell"], [role="gridcell"]');
if (cells.length < 3) return;
var impr = num(cells[2].textContent);
var ctrCell = [].find.call(cells, function (c) { return /%/.test(c.textContent); });
var ctr = ctrCell ? num(ctrCell.textContent) : 100;
if (impr >= 1000 && ctr < 1) {
r.style.background = '#fff3cd';
r.style.boxShadow = 'inset 3px 0 0 #b06000';
}
});
}
