gistfile1.txt

const save = () => JSON.stringify(Object.keys(localStorage).reduce((acc, curr) => { acc[curr] = localStorage.getItem(curr); return acc; }, {}));

// Usage in console:
copy(save());

// new console
o = CTRL+V
restore(o);

const clean = () => { Object.keys(localStorage).forEach(k => localStorage.removeItem(k)); return true };
const restore = (o) => clean() && Object.entries(o).forEach(([key, val]) => localStorage.setItem(key, val));
