macos – How to easily move all notes to another folder?

A co-worker resigned last week, and just returned his Macbook to the office.
Now I’m backing up all the data before deleting his Mac account.

He had plenty of notes stored in the Notes app. I don’t see a feature to export multiple notes to a zip file or Google Drive/Dropbox/etc. Sharing each one of them via email will be tedious.

I wonder if it’s possible to move them to USB flashdrive, for example.
