This workflow demonstrates how to automate the extraction of business emails from Google Maps results using a specific keyword. It streamlines the process of finding, filtering, and saving contact emails into a Google Sheet, eliminating the need for tedious manual research.

This tool is perfect for those who need to collect business email addresses for outreach, research, or marketing purposes, especially those whose success depends on building and managing business relationships at scale.

  • Sales and Lead Generation Teams: Quickly build targeted business email lists for efficient cold outreach and follow-up.
  • Marketing Agencies and Freelancers: Effortlessly gather contact details for potential clients in specific niches or locations to power outreach campaigns.
  • Recruiters and Talent Acquisition Specialists: Easily collect company contacts to connect with HR or hiring managers in targeted industries or regions.
  • Event Organizers and B2B Promoters: Rapidly compile relevant business emails for event invitations, sponsorship proposals, or promotional efforts.
  • Market Researchers and Data Analysts: Automate large-scale collection of business emails to support industry analysis and data-driven research.

How It Works

  • A target keyword (e.g., “n8n workflow”) should be entered in Node Fields - Set Keyword / Phrase.
  • Then, the process is triggered by clicking Test Workflow or Execute Workflow.
  • The workflow queries Google Maps, collects keyword-related website URLs from its HTML, and filters for only valid website URLs.
  • Next, it removes duplicate website URLs to ensure each is processed only once later.
  • For every unique valid website URL, the workflow sends an HTTP request to extract all potential email addresses from the website’s content in a loop.
  • After that, the emails are passed through another loop and a code node (Code – Match Email) to ensure each one is a valid, properly formatted email address (not just random text). Any invalid emails are filtered out during this step.
  • All valid emails are then collected and prepared for further processing.
  • The workflow then splits out the results and removes any duplicate emails to ensure each address appears only once.
  • Finally, the list of unique, verified emails (directly related to your chosen keyword) is saved to your connected Google Sheet for easy access and follow-up.

How To Set Up

  • Download the working package.
  • Import the package into your n8n interface.
  • Duplicate the Google Maps - Crawl Emails By Keyword Google Sheets template into your Google Sheets account.
  • Set up necessary credentials in Google Cloud Console for Google Sheets access and usability in Node Google Sheets - Update Data.
  • Set up a GET method to access Google Maps in Node HTTP Request - Get Sites.
  • Enter your desired keyword or phrase in Node Fields - Set Keyword / Phrase.
  • Start the workflow in n8n.
  • Wait a few minutes for the process to finish.
  • Check the list of all valid emails related to your keyword/phrase in the connected Google Sheet.

Requirements

  • Basic setup in Google Cloud Console (OAuth or API Key method enabled) with enabled access to Google Sheets.
  • Access to Google Maps.

How To Customize

  • Adjust the Keyword Input: You can easily change the keyword or phrase you want to search for by editing the second node, Fields – Set Keyword / Phrase, in your n8n workflow.
  • Add Follow-up Steps: Modify the workflow to even trigger follow-up actions like sending emails automatically.

Extract Business Emails from Google Maps Search Results to Google Sheets

This n8n workflow automates the process of extracting business emails from Google Maps search results and saving them into a Google Sheet. It's designed to help you quickly gather contact information for businesses based on specific search queries.

What it does

  1. Manual Trigger: Starts the workflow manually when you click "Execute workflow".
  2. Sticky Note: Provides a note for context within the workflow (not functional).
  3. HTTP Request: Makes an API call (likely to a service that scrapes Google Maps) to retrieve search results for a specified query.
  4. Loop Over Items: Iterates through each business found in the Google Maps search results.
  5. Edit Fields (Set): Extracts specific data points (e.g., business name, website, email) from each business's information.
  6. Filter: Checks if an email address was successfully extracted for the current business.
  7. Code: (Conditional) If an email is found, this node might perform additional processing or formatting of the email address.
  8. Remove Duplicates: Ensures that only unique email addresses are processed further, preventing redundant entries.
  9. Aggregate: Collects all the unique, extracted email addresses and their associated business details.
  10. Split Out: Prepares the aggregated data for insertion into Google Sheets, potentially flattening nested structures.
  11. Google Sheets: Appends the extracted business information (including emails) as new rows to a specified Google Sheet.

Prerequisites/Requirements

  • n8n Instance: A running n8n instance (self-hosted or cloud).
  • Google Sheets Account: A Google account with access to Google Sheets.
  • Google Sheets Credential: An n8n credential configured for Google Sheets (OAuth2 recommended).
  • Google Maps Scraper API: Access to a third-party API that can scrape Google Maps search results (e.g., a service that returns structured data for businesses). You will need to configure the HTTP Request node with the appropriate API endpoint and authentication.

Setup/Usage

  1. Import the Workflow: Import the provided JSON into your n8n instance.
  2. Configure Credentials:
    • Set up your Google Sheets credential in n8n if you haven't already.
  3. Configure HTTP Request Node:
    • Edit the HTTP Request node.
    • Replace the placeholder URL with the actual endpoint of your Google Maps scraper API.
    • Configure any necessary headers or query parameters for your API, including your search query (e.g., "restaurants in New York").
    • Add any required authentication (e.g., API key in headers or query parameters).
  4. Configure Google Sheets Node:
    • Edit the Google Sheets node.
    • Select your Google Sheets credential.
    • Specify the Spreadsheet ID and Sheet Name where you want the data to be written.
    • Ensure the "Operation" is set to "Append Row".
  5. Configure Edit Fields (Set) Node:
    • Verify that the fields being extracted (e.g., businessName, website, email) match the output structure of your Google Maps scraper API. Adjust the expressions as needed.
  6. Activate the Workflow: Once configured, activate the workflow.
  7. Execute Manually: Click "Execute workflow" on the Manual Trigger node to run the workflow and start extracting emails.

Automated UGC video generator with Gemini images and SORA 2

This workflow automates the creation of user-generated-content-style product videos by combining Gemini's image generation with OpenAI's SORA 2 video generation. It accepts webhook requests with product descriptions, generates images and videos, stores them in Google Drive, and logs all outputs to Google Sheets for easy tracking. Main Use Cases Automate product video creation for e-commerce catalogs and social media. Generate UGC-style content at scale without manual design work. Create engaging video content from simple text prompts for marketing campaigns. Build a centralized library of product videos with automated tracking and storage. How it works The workflow operates as a webhook-triggered process, organized into these stages: Webhook Trigger & Input Accepts POST requests to the /create-ugc-video endpoint. Required payload includes: product prompt, video prompt, Gemini API key, and OpenAI API key. Image Generation (Gemini) Sends the product prompt to Google's Gemini 2.5 Flash Image model. Generates a product image based on the description provided. Data Extraction Code node extracts the base64 image data from Gemini's response. Preserves all prompts and API keys for subsequent steps. Video Generation (SORA 2) Sends the video prompt to OpenAI's SORA 2 API. Initiates video generation with specifications: 720x1280 resolution, 8 seconds duration. Returns a video generation job ID for polling. Video Status Polling Continuously checks video generation status via OpenAI API. If status is "completed": proceeds to download. If status is still processing: waits 1 minute and retries (polling loop). Video Download & Storage Downloads the completed video file from OpenAI. Uploads the MP4 file to Google Drive (root folder). Generates a shareable Google Drive link. Logging to Google Sheets Records all generation details in a tracking spreadsheet: Product description Video URL (Google Drive link) Generation status Timestamp Summary Flow: Webhook Request → Generate Product Image (Gemini) → Extract Image Data → Generate Video (SORA 2) → Poll Status → If Complete: Download Video → Upload to Google Drive → Log to Google Sheets → Return Response If Not Complete: Wait 1 Minute → Poll Status Again Benefits: Fully automated video creation pipeline from text to finished product. Scalable solution for generating multiple product videos on demand. Combines cutting-edge AI models (Gemini + SORA 2) for high-quality output. Centralized storage in Google Drive with automatic logging in Google Sheets. Flexible webhook interface allows integration with any application or service. Retry mechanism ensures videos are captured even with longer processing times. --- Created by Daniel Shashko

Add Spending Analytics Extend the daily check-in to calculate: Weekly/monthly spending summaries Category-wise breakdowns Use additional Code nodes to process transaction history Important Notes ⚠️ Never trigger with normal messages - Only use app mentions (@botname) to avoid infinite loops where the bot replies to its own messages. 💡 Context Awareness - The bot remembers conversation history, so you can reference "yesterday", "last week", or previous transactions naturally. 🔒 Data Privacy - All your financial data stays in your Google Sheets and PostgreSQL database. The AI only processes transaction text temporarily. 📊 Backup Regularly - Export your Google Sheets periodically as backup. --- Pro Tips: Start with small test transactions to ensure everything works Use consistent person names for debt tracking The bot understands various formats: "₹500 cash food" = "paid 500 rupees in cash for food" You can batch transactions in one message: "₹100 travel, ₹200 food, ₹50 snacks"
