Below is a JavaScript implementation using Node.js and the googleapis library to update the descriptions of all your YouTube videos with headings. Create a project in the Google Cloud Console . Enable the YouTube Data API v3 . Generate OAuth 2.0 credentials and download the credentials.json file. Install Node.js and the required libraries: npm install googleapis fs const fs = require('fs'); const { google } = require('googleapis'); // Define the scope and API service name const SCOPES = ['https://www.googleapis.com/auth/youtube']; const TOKEN_PATH = 'token.json'; /** * Authenticate and return the YouTube API client. */ async function getAuthenticatedClient() { const content = fs.readFileSync('credentials.json'); const credentials = JSON.parse(content); const { client_secret, client_id, redirect_uris } = credentials.installed; const oAuth2Client = new google.auth.OAuth2(client_id, client_secret, redirect_uris[0]); // Check if we have previously stored a token if (fs.existsSync(TOKEN_PATH)) { const token = fs.readFileSync(TOKEN_PATH, 'utf8'); oAuth2Client.setCredentials(JSON.parse(token)); } else { const authUrl = oAuth2Client.generateAuthUrl({ access_type: 'offline', scope: SCOPES, }); console.log('Authorize this app by visiting this URL:', authUrl); const rl = require('readline').createInterface({ input: process.stdin, output: process.stdout, }); const code = await new Promise((resolve) => { rl.question('Enter the authorization code: ', (code) => { rl.close(); resolve(code); }); }); const { tokens } = await oAuth2Client.getToken(code); oAuth2Client.setCredentials(tokens); // Store the token for future use fs.writeFileSync(TOKEN_PATH, JSON.stringify(tokens)); console.log('Token stored to', TOKEN_PATH); } return google.youtube({ version: 'v3', auth: oAuth2Client }); } /** * Fetch all video IDs from the uploads playlist. */ async function fetchVideoIds(youtube) { const channelResponse = await youtube.channels.list({ part: 'contentDetails', mine: true, }); const uploadsPlaylistId = channelResponse.data.items[0].contentDetails.relatedPlaylists.uploads; let videoIds = []; let nextPageToken = null; do { const playlistResponse = await youtube.playlistItems.list({ part: 'contentDetails', playlistId: uploadsPlaylistId, maxResults: 50, pageToken: nextPageToken, }); videoIds = videoIds.concat(playlistResponse.data.items.map(item => item.contentDetails.videoId)); nextPageToken = playlistResponse.data.nextPageToken; } while (nextPageToken); return videoIds; } /** * Update the description of each video with a heading. */ async function updateVideoDescriptions(youtube) { const videoIds = await fetchVideoIds(youtube); for (const videoId of videoIds) { const videoResponse = await youtube.videos.list({ part: 'snippet', id: videoId, }); const video = videoResponse.data.items[0]; const snippet = video.snippet; const originalDescription = snippet.description || ''; // Add a heading to the description snippet.description = `=== Video Description ===

${originalDescription}`; // Update the video's description await youtube.videos.update({ part: 'snippet', requestBody: { id: videoId, snippet: snippet, }, }); console.log(`Updated description for video ID: ${videoId}`); } } (async () => { try { const youtube = await getAuthenticatedClient(); await updateVideoDescriptions(youtube); } catch (error) { console.error('Error:', error); } })(); Authentication : The script uses OAuth 2.0 to authenticate and gain access to your YouTube account. Fetching Videos : It retrieves all videos from your "uploads" playlist. Updating Descriptions : For each video, it appends a heading ( === Video Description === ) to the existing description and updates it using the YouTube Data API. Steps to Run: Save the script as update_youtube_descriptions.js . Place the credentials.json file in the same directory. Run the script: node update_youtube_descriptions.js

Part -1 To update the descriptions of all your YouTube videos with headings, you can use the YouTube Data API . If you want to do it programatically. An example implementation in Python using the google-api-python-client library. This script will fetch all your videos, append a heading to their descriptions, and update them. Before running the script: Create a project in the Google Cloud Console . Enable the YouTube Data API v3 . Generate OAuth 2.0 credentials and download the credentials.json file. Install the required library: pip install google-api-python-client google-auth-oauthlib google-auth-httplib2 . import os import pickle from googleapiclient.discovery import build from google_auth_oauthlib.flow import InstalledAppFlow from google.auth.transport.requests import Request # Define the scope and API service name SCOPES = ['https://www.googleapis.com/auth/youtube'] API_SERVICE_NAME = 'youtube' API_VERSION = 'v3' def get_authenticated_service(): """Authenticate and return the YouTube API client.""" creds = None if os.path.exists('token.pickle'): with open('token.pickle', 'rb') as token: creds = pickle.load(token) if not creds or not creds.valid: if creds and creds.expired and creds.refresh_token: creds.refresh(Request()) else: flow = InstalledAppFlow.from_client_secrets_file('credentials.json', SCOPES) creds = flow.run_local_server(port=0) with open('token.pickle', 'wb') as token: pickle.dump(creds, token) return build(API_SERVICE_NAME, API_VERSION, credentials=creds) def update_video_descriptions(youtube): """Fetch all videos and update their descriptions with headings.""" # Fetch the list of videos request = youtube.channels().list( part='contentDetails', mine=True ) response = request.execute() # Get the uploads playlist ID uploads_playlist_id = response['items'][0]['contentDetails']['relatedPlaylists']['uploads'] # Fetch all video IDs from the uploads playlist video_ids = [] next_page_token = None while True: playlist_request = youtube.playlistItems().list( part='contentDetails', playlistId=uploads_playlist_id, maxResults=50, pageToken=next_page_token ) playlist_response = playlist_request.execute() for item in playlist_response['items']: video_ids.append(item['contentDetails']['videoId']) next_page_token = playlist_response.get('nextPageToken') if not next_page_token: break # Update each video's description for video_id in video_ids: video_request = youtube.videos().list( part='snippet', id=video_id ) video_response = video_request.execute() if video_response['items']: video = video_response['items'][0] snippet = video['snippet'] original_description = snippet.get('description', '') # Add a heading to the description new_description = f"=== Video Description ===

{original_description}" # Update the video's description snippet['description'] = new_description update_request = youtube.videos().update( part='snippet', body={ 'id': video_id, 'snippet': snippet } ) update_response = update_request.execute() print(f"Updated description for video ID: {video_id}") if __name__ == '__main__': # Authenticate and get the YouTube service youtube = get_authenticated_service() # Update video descriptions update_video_descriptions(youtube) Authentication : The script uses OAuth 2.0 to authenticate and gain access to your YouTube account. Fetching Videos : It retrieves all videos from your "uploads" playlist. Updating Descriptions : For each video, it appends a heading ( === Video Description === ) to the existing description and updates it using the YouTube Data API. Steps to Run: Save the script as update_youtube_descriptions.py . Place the credentials.json file in the same directory. Run the script: python update_youtube_descriptions.py . Follow the prompts to authenticate your account.
