Narrative:

We just leveled off at 30;000 feet and flight attendant informed us that there was a smell of smoke in the cabin. Shortly thereafter; they called again and said that other flight attendants smelled the electric smoke smell as did [the] passengers. We were a few miles north of ZZZ at the time and elected to divert. Both the captain and I smelled an electric smell and donned our oxygen masks. The smell cleared in the cockpit and when we checked in with the flight attendants they said it had also cleared in the cabin. We [advised ATC] and asked for radar vectors to final approach to runway xxr. We coordinated with the flight attendants deciding not to do an evacuation and unless we heard from them that the condition worsened; we would land normally and have the fire trucks follow us to the gate where we would deplane normally. We landed and taxied to the gate as we planned; and the smell never returned. The entire crew did a great job coordinating and executing this abnormal event.
