If anyone want to export their list to anilist or a format supported by MAL, here’s a tool:

github[.]com/kitsu med/notify.moe-exporter

For anilist it should work as-is. For MAL, you will need to edit the file and add update_on_import set to 1 for every anime entry and it should work, I think…

There’s a few limitations, only the overall score is exported. Sometimes the activity database is missing event so there’s no start at/ended at date (default to year 1001-01-01 I think) but outside of that everything works.
