n8n GPT-4o Google Sheets Web Scraping AI Agent

GPT-4o Autonomous
Company Research Engine

Drop a list of company names into a Google Sheet. An autonomous GPT-4o agent scours the web, extracts critical firmographic data (LinkedIn URLs, pricing, tech stack, market focus, key decision-maker roles) and writes it back into the sheet. No API keys per company. No manual lookup.

Sales and marketing teams spend hours manually researching prospect companies before they can write a meaningful email or build a qualified list. Tools like Clearbit and ZoomInfo are expensive and often outdated. Most return what a company looked like 6 months ago.

This system uses live web research via a GPT-4o agent that searches and reads pages in real time. What you get is current, structured, and automatically organised and ready for outreach without a single manual lookup.

Sales Ops Teams

Building target account lists at scale. Upload 200 company names, come back to a fully enriched spreadsheet ready for segmentation.

SDRs & BDRs

Research that would take 15 minutes per company now takes seconds. Spend time on conversations, not browser tabs.

Demand Gen Marketers

Segment account lists by market focus, pricing tier, or tech stack. Fields that standard databases rarely include or keep updated.

Investors & Analysts

Quickly gather structured competitive intelligence across a portfolio of companies without hiring a research team.

1
Read Company List from Google Sheets

The workflow reads all rows in a designated Google Sheet where the status column is blank or "pending". It processes companies in batches to stay within API rate limits and avoid hitting Google Sheets quota. Each company name is passed to the AI agent as a separate task.

GPT-4o Agent Deploys Web Research

An autonomous GPT-4o agent is equipped with Google Search and web scraping tools. For each company, it runs targeted searches: company homepage, LinkedIn company page, Crunchbase or G2 profile, recent press. It reads each page and extracts structured data points.

Structured Data Extraction

The agent extracts and structures: LinkedIn company URL, website, employee count, HQ location, primary market (B2B/B2C/both), pricing model, key integrations and tech stack, main product category, ideal customer profile, and any recent funding or news. Output is a clean JSON object, no hallucinated data, only what the agent actually finds.

Sheet Write-Back

Each field from the JSON object maps to a column in the original Google Sheet. The row is updated in place. No new rows created, no formatting broken. Status column is set to "enriched" so re-runs skip completed entries. Failed lookups are flagged as "review" for manual fallback.

CRM or Outreach Push (Optional)

Once enriched, rows can be automatically pushed to HubSpot as new companies, added to a Clay table for further waterfall enrichment, or exported to Instantly as a targeted campaign segment. The sheet becomes a clean handoff layer between research and outreach.

1
Prepare Google Sheet

Create a sheet with a "Company Name" column and blank columns for each output field: LinkedIn, Website, Employees, Location, Market, Pricing, Tech Stack, Product Category, ICP, News, Status. Share the sheet with the service account or connect via OAuth2.

2
Configure GPT-4o in n8n

Add your OpenAI API key to n8n credentials. Set model to gpt-4o. Configure the AI Agent node with tools: Google Search and HTTP Request (for web scraping). Set max iterations to 8 per company to control costs.

3
Write the Research Prompt

The system prompt tells the agent exactly what to find and how to structure the JSON output. Specify field names, acceptable values for categorical fields (e.g. market: "B2B" | "B2C" | "Both"), and instructions to leave fields blank rather than hallucinate.

4
Test with 3 Companies

Run manually with 3 known companies you can verify. Check that returned data is accurate, fields map correctly to the sheet, and status updates properly. Adjust the prompt if any fields return inconsistently.

5
Schedule or Trigger

Set a daily schedule to process new rows automatically, or trigger manually when you upload a new batch. Add a Slack notification node to alert you when a batch completes.
