🧑 Instructions for ingesting your Google Docs data
By default, the GoogleDriveLoader
expects the credentials.json
file to be ~/.credentials/credentials.json
, but this is configurable using the credentials_file
keyword argument. Same thing with token.json
. Note that token.json
will be created automatically the first time you use the loader.
GoogleApiYoutubeLoader
can load from a list of Google Docs document ids or a folder id. You can obtain your folder and document id from the URL:
Note depending on your set up, the service_account_path
needs to be set up. See here for more details.
