Manually going through spreadsheets to score new leads slows down your sales pipeline and eats into productivity. With lead qualification automation, you can instantly decide which leads are worth following up — without human bottlenecks.
This guide will show you how to set up an AI-powered workflow to qualify leads with GPT-4 in Google Sheets. Using Google Sheets as the entry point and OpenAI’s GPT-4 as the decision engine, new leads are automatically checked against your rules and scored as “qualified” or “not qualified.”

Workflow: Qualify Leads with GPT-4 in Google Sheets
This n8n workflow integrates Google Sheets and OpenAI’s GPT-4 for real-time lead evaluation.
Key Components
- Google Sheets Trigger
- Node: Check for new entries
- Watches for new form submissions in Google Sheets and triggers the workflow.
- Lead Qualification with GPT-4
- Node: Qualify leads with GPT
- Sends name, email, business area, and team size to GPT-4.
- GPT-4 returns JSON with rating (“qualified” or “not qualified”) + explanation.
- JSON Extraction and Parsing
- Node: Extract JSON reply
- Ensures GPT-4’s response is structured properly.
- Data Merging and Update
- Node: Merge – Combines original row with GPT-4’s result.
- Node: Update lead status – Writes back the “Rating” and timestamp into the Google Sheet.
- Sticky Notes
- Provide setup tips, qualification logic, and update guidance.
How the Workflow Qualifies Leads
Step 1: Triggering from Google Sheets
The workflow starts with Check for new entries, which monitors a designated Google Sheet for new rows.
Step 2: Extracting Lead Data
Each new row contains:
- Email Address
- Name
- Business area
- Team size
Step 3: Qualifying with GPT-4
The Qualify leads with GPT node evaluates the data against two rules:
- Decision-making authority and team size.
- Email domain type (corporate preferred).
It returns a JSON response like:
{“rating”: “qualified”, “explanation”: “Lead has a corporate email and manages a team.”}
Step 4: Parsing JSON
The Extract JSON reply node ensures clean parsing of GPT-4’s output.
Step 5: Merging Data
The Merge node combines the original row data with GPT’s qualification result.
Step 6: Updating Google Sheets
Finally, the Update lead status node writes:
- Qualification rating
- Timestamp
- Explanation
directly into the Google Sheet.
