If, like me, you have the opposite scenario with Apple Notes (migrating 1 very-large note into Obsidian instead of numerous small ones), the solution is different :
- Create a new file in TextEdit on Mac or Notepad on Windows, in the menubar make sure the format selected is Plain Text not Rich Text
- go back to where the notes originally are, select all, copy, paste into TextEdit or Notepad
- then select all in there, copy, switch to Obsidian, New Note, paste without formatting (Paste and Match Style under ‘Edit’ - or Command + Option + Shift + v then select “unformatted text”. In windows, it’s Ctrl + Alt + Shift v then select "unformatted text”).
This is important because for some reason, when pasting from a non-standard multimedia featured-notes tool, markdown editors seem to parse unknown code as extra carriage-returns (blank enter-spaces), which creates a problem if you plan to do text analytics or formatting-retention is otherwise essential.
