Yahoo account in Notes app

Hey there and welcome to Apple Support Communities zz8daniel,

We can certainly understand your concern and can help provide some insight.

We recommend checking out these steps for more information on how to import and export notes on your device.

"Import and export notes on Mac

You can import text files into Notes or export notes as PDF files.

Tip: If you keep notes in internet accounts—for example, iCloud, Google, Yahoo, or AOL—you can add those accounts to Notes on your Mac to access all your notes in one place without importing each note one by one. See Add or remove accounts in Notes.

Import text files into Notes

If you use upgraded iCloud notes or notes stored on your Mac, you can import text files into Notes as individual notes. You can import files in TXT, RTF, RTFD, HTML, or Evernote XML Export (ENEX) format.

If you have macOS Ventura 13 or later, you can also import tags from Evernote (ENEX) files.

1. In the Notes app  on your Mac, in the sidebar, click a folder in the account (iCloud or On My Mac) you want to import files into.
2. Choose File > Import to Notes.
3. Select one or more files, or select a folder to import all the text files in it. If you select a folder, click “Preserve folder structure on import” to keep the imported notes organized the way they were in the folder. (If you don’t see this option, click Options.)
4. Click Import.

Your new notes (and folders, if you imported any) appear in an Imported Notes folder. You can now move or rename the notes and folders as usual. See About accounts and folders.

Tip: To add non-text files, such as PDFs or image files, into Notes, you can simply attach them to a note. See Attach photos, files, and more.

Export a note

You can export notes as PDF files.

1. In the Notes app  on your Mac, click the note you want to export.
2. Choose File > Export as PDF.

If you want, you can type a new name for your PDF, and add tags that you can search for in the Finder.

3. Click Save. "
