A pop-up message appeared at the end of an attempted import saying the "errors" occurred. It asked if I wanted to report the incident and I agreed. If you need to see the imported file, tell me it was "History" from Notebook Stack 2.
How many notebook files from Evernote have you tried importing?
I came from Evernote also and I found that not 100% of my notebooks imported properly.
Have you tried a few different notebooks?
You can put a lot of different kinds of stuff in an Evernote notebook. I can understand from my own experience that Joplin can get confused on one notebook but not another notebook, just based on the content of the notebook.
If you have an ENEX file that has no personal or sensitive information in it and also doesn't import, that would be a good file to post here (so we can try and import it as a test to see if it works on other installations).
Another tact:
Here is a link to a Joplin note that I published that talks about different free tools that you can use to convert an Evernote .enex file into a series of Markdown files. These extensions are supposedly very good at preserving as much of the Evernote content as possible but again you need to remember that Markdown is a very simple language for formatting text. Evernote is far more complex with what you can do inside a note.
Thank you for your response. Claude Code analyzed the file and told me that the error message resulted from an internal link in a note having a broken target. The note was otherwise loaded correctly. The only maintenance called for would be a better error message. I will attempt to find one of the notes which displayed the message.
