Unfortunately, none of the posted scripts worked for me. It's possible, based on the dates of the posts, they're out of date. I found a user on github who does have a fully functional script, with various output options.
Courtesty of jmiserez, go to your songs library in Google Play Music, make sure you're at the top of the page, then press F12 in Chrome. In the window that opens, click on "Console". At the prompt (>), paste the following script, then press enter:
// Jeremie Miserez <jeremie@miserez.org>, 2016
//
// A little bit of Javascript to let you export your Google Music library, playlists, and album track lists :)
//
// I posted this as an answer here: http://webapps.stackexchange.com/questions/50311/print-playlist-from-google-play-music
//
// 1. Go to: https://play.google.com/music/listen#/all (or your playlist)
//
// 2. Open a developer console (F12 for Chrome). Paste
// code below into the console.
//
// 3. All scraped songs are stored in the `allsongs` object
// and a text version of the list is copied to the clipboard. I recommend running
// `songsToText("all",true)` afterwards to get the full CSV information.
//
// 4. If you would like the output in a text format, can call
// the songsToText() function. You can select a style, choose
// the format, and if only liked/thumbed up songs should be exported.
// The resulting list will then be pasted into the clipboard.
// Styles are ` all`, `artist`, `artistalbum`, `artistsong`,
// `artistalbumsong`.
// CSV will result in a CSV file and can be left out (defaults to false).
// Likedonly can be left out (defaults to
// false) or set to true, and will filter all songs with
// ratings greater or equal to 5.
// E.g:
// - `songsToText("all",true,false)` will export all songs in csv format.
// - `songsToText("all",true,true)` will export only liked songs in csv format.
// - `songsToText("artistsong",false,false)` will export all songs as text.
//
// 5. You can then paste the data anywhere you like, for
// example http://www.ivyishere.org/ if you want to add the
// songs or albums to your Spotify account. To make Ivy
// recognize full albums, use the "artistalbum" style. For
// songs, use the "artistsong" style.
// see my answer here for questions: http://webapps.stackexchange.com/a/73791/77056

When it's done running, you can scroll down and see your entire song list. Select it all, and copy, then paste it into a spreadsheet. You're doing this so you can select your songs in groups of 500.
Select the first 500 songs from your spreadsheet, then go to:
http://www.playlist-converter.net/#/
Paste in your selection of 500 songs. Click "Convert". When it is done, for your output, select the Spotify URI, then copy all the URI codes it generates.
Go to your Spotify app and select "Songs". Then press Cntrl + V. This will add all 500 songs. It will skip any songs you already have in your Spotify library.
Now do your next 500 from your spreadsheet, to the playlist converter, to outputting to Spotify URIs, to pasting them into the Spotify app in your songs library. Keep rinsing and repeating.
I use 500 songs, as that appears to be the limit on how many Spotify URIs that the playlist converter will spit out at once, regardless of how many songs you had input.
All credit to jmiserez on github. This was a painless way for me to finally move nearly my entire Google Play Music library of thousands of songs to Spotify.
