Since the old Lanyrd site was back up over the weekend, I went in and saved all of the old data I wanted from it before it decided to shut down again (there is no news on when this may happen). Sadly there is no direct export, but I was able to save pages individually and/or save them to the Internet Archive.
I also just noticed that notist seems to have a relatively nice import/export path which may also be available for some too. I love that their site says this:
One thing we very much believe in is that you should own your own data. As such, we didn’t want to just suck your data into Notist and leave it at that. Instead, we’ve built a tool that gives you access to the content as HTML and JSON, ready for you to take away today.
