How do I import a Reminder.app lists into a Notes.app checklist?
The following AppleScript script will take the selected Reminders in Reminders and make a new Note in Checklist format in Notes. This can be run in Script Editor or saved as an AppleScript application. 


Note: As this script uses UI Scripting, when run from Script Editor, it must be added to System Preferences > Security &amp; Privacy > Accessibility in order to run. As an AppleScript application, the application would need to be added.




tell application "Reminders" to activate
delay 0.1
tell application "System Events" to keystroke "c" using {command down}
delay 0.1
set theNotesChecklist to ""
set theReminders to get the clipboard as string
repeat with thisParagraph in paragraphs of text of theReminders
    try
        set theNotesChecklist to theNotesChecklist &amp; text 5 thru -1 of thisParagraph &amp; return
        delay 0.1
    end try
end repeat
tell application "Notes" to activate
tell application "System Events"
    keystroke "n" using {command down}
    keystroke "l" using {shift down, command down}
    delay 0.5
    keystroke theNotesChecklist
    delay 0.1
    key code 51 -- # Delete - Deletes the last 'return' typed.
end tell


The above script assumes the selected Reminders in Reminders have no information associated with them. In other words, other then the Name property no other associated properties have been set. If other properties have been set, add the if statement to the repeat loop as shown in the code below:

repeat with thisParagraph in paragraphs of text of theReminders
    try
        if thisParagraph starts with "[ ]" then
            set theNotesChecklist to theNotesChecklist &amp; text 5 thru -1 of thisParagraph &amp; return
            delay 0.1
        end if
    end try
end repeat


Note: With UI Scripting, the value of the delay commands may need to be changed on your system and or additional delay commands added as appropriate.
