This tool is still a bit of a work in progress. Use the Import button above, and import your Beat Saber PlayerData.dat file (should be in C:/Users/USERNAME/AppData/LocalLow/Hyperbolic Magnetism/Beat Saber) to render out a list of your liked tracks! No data leaves this page (minus the required song hashes for use with BeatSaver's API).
All data is cached client-side, each song will only fetch data from BeatSaver once. The initial import may be slow!
