LikesR is a browser-based viewer and exporter for YouTube likes and watch history from a Google Takeout file. It imports ZIP, TGZ, JSON, HTML or playlist CSV files. You can search titles, channels and video IDs, sort oldest or newest, filter by year and see a yearly chart.
Export to CSV, JSON, offline HTML or browser bookmarks, with no export limits. Files never leave the browser, with no upload, no sign-in and no server database. The tool is free to use.
YouTube's liked-videos playlist only displays about 5,000 items, while likes in a Google Takeout export can go beyond that. LikesR reads the export locally in the browser so you can search, filter, and export them without uploading the file.
