I exported all my spotify data by going to Account > Privacy Settings on their website and requesting all the data that I could get.

This included:

    -Playlists
    -Streaming history for the past year (you can request history for the lifetime of your account too)
    -A list of items saved in your library
    -Search queries
    -No. of followers, accounts you follow, and blocked accounts
    -Payment and subscription data
    -User data
    -Family Plan data
    -Inferences
    -Voice input
    -Podcast interactivity
    -Spotify for Artists data

I used this data to buy the music I wanted to keep and make my own collection.

You can also export all of the data about your playlists and library from Spotify's public APIs: developer.spotify.net
