I seem to recall dumping Planner to JSON easily enough. I don't know if you can easily restore directly from its JSON, but the JSON was nice enough to work on for what little I needed to do with it.
My current employer shut off Trello and forced us over to Jira and is threatening to disable Planner, so I'm "not allowed" to rely on Planner enough day-to-day so it's possible it is either better or worse than I remember it being in that department. But this Jira outage has me reevaluating, and they haven't turned off Planner yet.
