There’s actually a web app that does exactly what you are describing. It seamlessly converts playlists between apple music to spotify and vice versa. Check it out https://playlistor.io/ .
Thank you! This is really close. It doesn't solve my personal need but it may work for others.
It only works with Apple Music, which isn't the app I use. Also, when I paste a public Spotify playlist URL (source), it asks for my Apple Music credentials instead of creating a public Apple Music playlist or if that's not possible, generating a page with play links.
Still, it's trying to solve the same problem and may work for others. I appreciate the link.
You are welcome. With spotify to Apple music conversion, your credentials are needed because the Apple music endpoint requires the user to be authenticated to be able to create playlists. Also, after a successful conversion, the links to each platforms playlist is listed on the web app. I thank you for checking it out.
My experience in trying this recently was that https://www.tunemymusic.com/ was able to match more of my iTunes library to Spotify than Playlistor, but YMMV.
