Automate call center sentiment analysis with GPT-4o-mini and Google Sheets

✅ What problem does this workflow solve?

Call centers often record conversations for quality control and training, but reviewing every transcript manually is tedious and inefficient. This workflow automates sentiment analysis for each call, providing structured feedback across multiple key categories, so managers can focus on improving performance and training.

⚙️ What does this workflow do?

1. Accepts a Google Sheet containing:
   • Call transcript
   • Agent name
   • Customer name
2. Analyzes each call transcript across multiple sentiment dimensions:
   • 👋 Greeting Sentiment
   • 🧑‍💼 Agent Friendliness
   • ❓ Problem-Solving Sentiment
   • 🙂 Customer Sentiment
   • 👋 Closing Sentiment
   • ✅ Issue Resolved (Yes/No)
3. Add Conversation Topics discussed in a call
4. Calculates an overall call rating based on combined analysis.
5. Updates the Google Sheet with:
   • Individual sentiment scores
   • Issue resolution status
   • Final call rating

🔧 Setup Instructions

📄 Google Sheets

The workflow will append results in new columns automatically:

🧠 How it Works – Step-by-Step

1. Sheet Scan – The workflow reads rows from the provided Google Sheet.
2. Loop Through Calls – For each transcript, it:
   • Sends prompts to OpenAI to analyze:
     • Greeting tone (friendly/neutral/rude)
     • Problem-solving quality (clear/confusing/helpful)
     • Closing sentiment
     • Agent attitude
     • Customer satisfaction
     • Whether the issue was resolved
   • Calculates a composite rating from all factors.
