Automate LINE to Google Sheets: Gemini for Business Cards

Transform Business Card Photos into Organized Contact Data Instantly

Stop wasting time manually typing business card information after networking events. This powerful n8n workflow automates the entire process for Japanese sales professionals and account managers by combining LINE messaging, Google Gemini AI, and Google Sheets integration. Simply snap a photo of any business card, send it to your LINE bot, and watch as AI extracts and organizes all contact details automatically.

What This Workflow Does

When you send a business card photo to your configured LINE bot, Google Gemini AI intelligently extracts key contact information including name, company, job title, phone number, email address, and postal address. The workflow automatically saves this structured data to your Google Sheets spreadsheet while checking for duplicate entries based on email addresses to maintain clean records. Your team stays informed through instant Slack notifications whenever new contacts are added to your database.

Perfect Use Cases

• Sales professionals attending trade shows and networking events who collect dozens of business cards
• Account managers building comprehensive client contact databases
• Business development teams streamlining lead capture and follow-up processes
• Small businesses eliminating manual data entry bottlenecks in their sales pipeline

Technical Integration Details

This workflow leverages multiple powerful integrations through n8n nodes including webhook triggers, HTTP requests, conditional logic, and data processing capabilities. The automation connects LINE Messaging API for photo receipt, Google Gemini AI for intelligent text extraction, Google Sheets for data storage, and Slack for team notifications. Setup requires LINE Messaging API credentials, Google Gemini API access, and Slack webhook configuration.

The workflow includes smart duplicate detection and can be easily customized to match your existing CRM field structure.
