Migrate from Nimbus - my journey

Migrate from Nimbus - my journey

TL;DR
the best tool I found to migrate out from from Nimbus Notes: https://github.com/kevindurston21/YANOM-Note-O-Matic

Long version
I was trying to find my perfect note-taking app for many years. For many years I was using Evernote but was disappointed with it and tried to find an alternative. As some stage I discovered Nimbus Notes and it looked very promising for me. The best feature I missed from Evernote is unlimited folder hierarchy (Evernote allows only one folder and one stack, so essentially maximum two levels of folder hierarchy).
I tried to migrate to Nimbus several times but always came back to Evernote.
Until October 2020 when Evernote released horrible (IMO) version 10 which became so unusable. I used previous functioning version until they blocked ability to login from old versions.
Then I migrated to Nimbus and I tried to be loyal, I was reporting bugs and feature requests. But at the end I gave up, too slow overall which is unacceptable (IMO) for the note-taking app.
Currently I am living happily with Obsidian.md, it is super fast, notes are lightweight and in readable markdown.
The problem was to migrate my notes out of Nimbus. With all due respect, Nimbus export functionality is horrible (IMO).
Luckily I found a tool that helps to simplify out-of-Nimbus-migration-process: https://github.com/kevindurston21/YANOM-Note-O-Matic
It is not perfect, because Nimbus export doesn't include some metadata such as note updated date.
Luckily I found Nimbus database which is json-based so I could write some scripts to extract essential to me metadata
