Who Is This For?

This workflow is perfect for anyone who wants to automate lead generation using n8n without paying for expensive scraping tools. It uses simple Google Maps API requests and Google Sheets to pull business data by ZIP code and category, then extracts emails at no extra cost.

What This Workflow Does

  • Automated Lead Generation: Runs on a schedule to process ZIP codes and business categories automatically.
  • Data Extraction: Queries Google Maps for businesses based on each ZIP code + subcategory combo.
  • Data Processing:
    • Skips entries with a STATUS = "N/A"
    • Removes duplicate results using place.id
    • Extracts and formats relevant business details
  • Error Handling:
    • Uses exponential backoff when hitting rate limits
    • Stops after 10 retry attempts
  • Data Storage:
    • Saves results directly to Google Sheets
    • Tracks which ZIP/subcategory pairs have been completed

Requirements

  • Google Maps API (business lookup)
  • Google Sheets OAuth2 (data storage)
  • Telegram Bot API (notifications)
  • Rapiwa API (WhatsApp alerts)

How to Use — Step-by-Step Setup

1. Set Up Credentials in n8n

  • Add your Google Maps API credentials (named "Google MAP")
  • Add Google Sheets OAuth2 credentials (named "Google Sheets")
  • Add Rapiwa API credentials (named "Rapiwa account 2")

2. Prepare Your Google Sheet

Create one Sheet document with these tabs:

  • zip — ZIP codes to process
  • maps categories — Business categories/subcategories
  • result — Where extracted business data will be stored Then update:
  • The document ID inside the workflow nodes
  • The sheet IDs (gid values) so they match your actual tabs

3. Customize the Workflow

  • Change the Limit node to control how many ZIP codes run per batch (default: 10)
  • Adjust retry limits in the relevant nodes (default: 10 attempts)
  • Modify the Schedule node to set your preferred run frequency (default: hourly) > This gives you a simple, scalable, nearly free system for generating targeted leads automatically.

Zip Code Based Business Lead Generation with Google Maps and Sheets

This n8n workflow automates the process of generating business leads based on a provided zip code, leveraging the Google Maps Places API and Google Sheets. It fetches business data, filters out duplicates, and stores the enriched leads in a Google Sheet. It also includes optional notifications via Telegram or Discord for successful runs or when no new leads are found.

What it does

  1. Triggers on a Schedule: The workflow starts on a predefined schedule (e.g., daily, weekly).
  2. Fetches Zip Codes: Reads a list of zip codes from a Google Sheet.
  3. Loops Through Zip Codes: Processes each zip code individually.
  4. Generates Google Maps API URL: Constructs a Google Maps Places API URL using the zip code and a predefined business type (e.g., "restaurants", "dentists").
  5. Fetches Business Data: Makes an HTTP request to the Google Maps Places API to retrieve business information for the given zip code and business type.
  6. Extracts Relevant Fields: Processes the API response to extract key business details such as name, address, phone number, and website.
  7. Checks for Existing Leads: Reads existing leads from a "Leads" sheet in Google Sheets to avoid duplicates.
  8. Filters New Leads: Compares the fetched business data with existing leads and filters out any duplicates.
  9. Limits New Leads (Optional): If configured, limits the number of new leads added in a single run.
  10. Appends New Leads to Google Sheet: Adds the unique, new business leads to the "Leads" Google Sheet.
  11. Sends Success Notification: If new leads are added, sends a success message with the count of new leads to Telegram or Discord.
  12. Sends No New Leads Notification: If no new leads are found, sends a notification to Telegram or Discord.

  4. Google Maps Places API Key:
    • Locate the "HTTP Request" node.
    • Update the URL to include your Google Maps Places API key.
  5. Business Type:

🎓 How to transform unstructured email data into structured format with AI agent

This workflow automates the process of extracting structured, usable information from unstructured email messages across multiple platforms. It connects directly to Gmail, Outlook, and IMAP accounts, retrieves incoming emails, and sends their content to an AI-powered parsing agent built on OpenAI GPT models. The AI agent analyzes each email, identifies relevant details, and returns a clean JSON structure containing key fields: From – sender’s email address To – recipient’s email address Subject – email subject line Summary – short AI-generated summary of the email body The extracted information is then automatically inserted into an n8n Data Table, creating a structured database of email metadata and summaries ready for indexing, reporting, or integration with other tools. --- Key Benefits ✅ Full Automation: Eliminates manual reading and data entry from incoming emails. ✅ Multi-Source Integration: Handles data from different email providers seamlessly. ✅ AI-Driven Accuracy: Uses advanced language models to interpret complex or unformatted content. ✅ Structured Storage: Creates a standardized, query-ready dataset from previously unstructured text. ✅ Time Efficiency: Processes emails in real time, improving productivity and response speed. *✅ Scalability: Easily extendable to handle additional sources or extract more data fields. --- How it works This workflow automates the transformation of unstructured email data into a structured, queryable format. It operates through a series of connected steps: Email Triggering: The workflow is initiated by one of three different email triggers (Gmail, Microsoft Outlook, or a generic IMAP account), which constantly monitor for new incoming emails. AI-Powered Parsing & Structuring: When a new email is detected, its raw, unstructured content is passed to a central "Parsing Agent." This agent uses a specified OpenAI language model to intelligently analyze the email text. Data Extraction & Standardization: Following a predefined system prompt, the AI agent extracts key information from the email, such as the sender, recipient, subject, and a generated summary. It then forces the output into a strict JSON structure using a "Structured Output Parser" node, ensuring data consistency. Data Storage: Finally, the clean, structured data (the from, to, subject, and summarize fields) is inserted as a new row into a specified n8n Data Table, creating a searchable and reportable database of email information. --- Set up steps To implement this workflow, follow these configuration steps: Prepare the Data Table: Create a new Data Table within n8n. Define the columns with the following names and string type: From, To, Subject, and Summary. Configure Email Credentials: Set up the credential connections for the email services you wish to use (Gmail OAuth2, Microsoft Outlook OAuth2, and/or IMAP). Ensure the accounts have the necessary permissions to read emails. Configure AI Model Credentials: Set up the OpenAI API credential with a valid API key. The workflow is configured to use the model, but this can be changed in the respective nodes if needed. Connect the Nodes: The workflow canvas is already correctly wired. Visually confirm that the email triggers are connected to the "Parsing Agent," which is connected to the "Insert row" (Data Table) node. Also, ensure the "OpenAI Chat Model" and "Structured Output Parser" are connected to the "Parsing Agent" as its AI model and output parser, respectively. Activate the Workflow: Save the workflow and toggle the "Active" switch to ON. The triggers will begin polling for new emails according to their schedule (e.g., every minute), and the automation will start processing incoming messages. --- Need help customizing?
