This script retrieves information about movies in the playlist you provided and shows the statistics of those movies with the use of Google Sheets. Thanks to this, you can compare all videos from a given playlist. The project with the use of Google Sheet and Google Apps Script allows you to check information on various parameters of videos in a given playlist using YouTube Api (of course, they can be playlists on a different account than yours). Thanks to this, we can observe the popularity and interest in subsequent films, and whether they like them.
