Standard Notes is a free, open source and multiplatform notes app. As an another advantage, it comes with a well-designed JSON format used for ex/import of all user data in Standard Notes.
This repo contains some tools for Standard Notes.
- Unfortunately, after importing a JSON file twice, the notes will be present twice. Though the files uniquely identify every note through a UUID, that is not used and new UUIDs are given. Thus it's not possible to simply externally modify and then re-import the notes. However, Standard Notes provides a way to completely reset the account (without loosing Extended status), and as the JSON contains all user data, that works actually pretty good.
