Youtube Transcript Downloader aka yt-transcript-downloader

A Firefox Extension that allows you to download the Transcripts of Youtube Videos as JSONs. Perfect for all your Youtube Historian and Research needs!

You can use it here: https://addons.mozilla.org/en-US/firefox/addon/youtube-transcript-downloader/

Results

After hitting the vanilla Show transcript button

You now get a new download button that you can click on to download the transcript as a JSON

The format of the JSON is the following:

{ "title": <title>, "url": <url>, "sections": [{ "name": , "lines": [{ <time>: <line> }, ...] }, ...] }

Youtube videos without sections just have one section with a blank name

How it works

It takes the transcript tab, converts it to text, and the does some custom parsing in order to turn it into a JSON file containing all metadata from the transcript that could be needed.
