A simple javascript code snippet to scrap video list from a youtube playlist. Just open up the playlist in a new tab. Go to Console, paste the code and boom!!! ProTip: Copy the console log to clipboard and then paste the clipboard contents to a newly created .csv file. You will have your required data in a nice clean format.

for(i=0; i < playlist.length; i++){
  video = playlist[i].innerText.replace(',','').split('\n') // converts "videoname, title, views" => "videoname title views"
  videoNames += video.toString() +"\n"
