How it Works

This workflow automates the collection and analysis of YouTube comments from a video and sends a summary report via email, using Google Sheets, the YouTube API, OpenAI (GPT-4o), and Gmail.

Whether you're a content creator, brand manager, or social media analyst, this workflow helps you automate sentiment analysis and receive insights directly in your inbox — all triggered from a simple spreadsheet.

🎯 Use Case

Ideal for:

  • YouTubers monitoring audience sentiment
  • Marketing teams analyzing campaign feedback
  • Community managers summarizing engagement

Setup Instructions

1. Upload the Spreadsheet

  • File name: Youtube_Video
  • Sheet structure:

  • Add video IDs and set their Status as Pending

2. Configure Google Sheets Nodes

Connect your Google account to:

  • Pick Video IDs from Google Sheet
  • Update Status on Google Sheet

3. Add API Credentials

  • YouTube API Key → for comment + video scraping nodes

  3. Analyze sentiment and key themes via GPT-4o
