Retrieve Notes from a Backup of your iPhone, iPad or iPod Touch
The iPhone Notes app is great for making quick notes to yourself, be it shopping lists, lecture notes, or reminders. These notes get backed up as part of your backup when you sync your iPhone with iTunes (or Finder if you are using macOS Catalina or higher), so you can recover important notes if anything happens to the device or if the notes get accidentally deleted.
Unfortunately, you cannot directly access your notes in it's backup files. For this reason, to retrieve your notes, you can either perform a full restore from the backup to your iOS device, or use software like iBackup Extractor to extract the notes from the backup and save them to your computer.
