Description of your issue, suggested solution and other information

Used youtube-dl to retrieve json objects of a user's youtube history. Relevant fields from the json files are title and categories. After filtering by the category 'Music,' trying to parse titles into 'artist' and 'title' - but this isn't 100% accurate.

Is there a way that youtube-dl will allow for parsing of this data? Will working with the --add-metadata or --metadata-from-title be able to parse the artist and title cleanly (especially if the audio or video isn't needed)?

--add-metadata or --metadata-from-title are postprocessing options thus only work during media postprocessing stuff. Metadata extracted via --metadata-from-title is not reflected in exported JSON.
