Some good solution to import notes from the other notepad apps

Is your feature request related to a problem? Please describe.
I wish I could move my old notes from other apps to this app, but there's no quick and easy way to import exported notes in any popular file format. Manual copy-pasting a hundred of notes is not a great idea.

Describe the solution you'd like
There are some apps with json files import, but the most popular and compatible way is definitely importing (and exporting) to the txt files.

Describe alternatives you've considered
The only way that may work is to copy files to the sync folder, but there's no popular notepad app which uses .org files, so that requires a lot of work to edit e.g. many txt files to fit in .org files formatting. Manual copying and pasting content of hundreds of notes becomes similar workaround.

Additional context
It would be great to have an option to export notes to the .txt files as well. If it would be considered as a valuable idea to add such feature to the import, then adding it to the export probably wouldn't be too much work.

The issue names no files, tests, or entry points. Start by locating the existing note import and export flows, then review how notes are stored and how JSON or TXT files could be handled. Done means users can import exported notes from common apps and export notes as TXT files without manual conversion.
