Export your Netflix ratings as a JSON file

export-netflix-ratings.js

// When viewing your Netflix activity at https://www.netflix.com/MoviesYouveSeen
// there's a "Download All" button at the bottom that allows you to export
// your entire viewing history as a CSV file.
// Unfortunately there is no equivalent button to export your ratings.
// This short JavaScript fragment lets you export your ratings as a JSON file.
// Just navigate to the ratings page, open your browser's Developer Tools,
// select the Console tab and paste this fragment. After it has run, you should
// be able to copy the output and save it into a file with the ".json"
// extension.
