export Data in localStorage for later re-import

Here’s how to import/export your entire localStorage

Export

copy(JSON.stringify(localStorage));

This will copy your localStorage to your clipboard. (You need two JSON.stringify()’s to get the quotes escaped.)

Import

var data = JSON.parse(/*paste stringified JSON from clipboard*/);
Object.keys(data).forEach(function (k) {
  localStorage.setItem(k, JSON.stringify(data[k]));
});
