Is it possible to export your own posts to json or anything currently? I like messing with data for archival. If not is it a planned feature? Could I perhaps host an instance just for archival purposes? If so how could I use instance hosting to best export and save data in a machine-processable format.
No it’s not possible with the current tools on Lemmy. You’re indeed better off askin the Lemmy devs on Github if you want a reply to that.
