We all know the feeling, you attend a conference, networking event, or client meeting, and come back with a stack of business cards. A week later, they’re either sitting forgotten on your desk or you’ve spent hours manually typing names, emails, and phone numbers into your CRM or spreadsheet. 
So I decided to automate the process with n8n + GPT-4o + Google Sheets, and here’s what the workflow does:
What this workflow does
-
Capture the card
You upload an image of a business card (from your phone, email, or any storage service).
-
Extract contact details with GPT-4o
Using GPT-4o’s multimodal capabilities, the workflow reads the card image and intelligently extracts structured data like:
-
Name
-
Job Title
-
Email Address
-
Phone Number
-
Company
-
-
Store into Google Sheets
The parsed information is automatically added into a Google Sheet—perfect for organizing your leads, syncing with CRMs, or sharing with your team.
Why this is useful
-
Save time: No more manual data entry.
-
Stay organized: Contacts go straight into a structured database.
-
Scalable: Works for a handful of cards or hundreds from an event.
-
Customizable: You can easily adapt it to push data into Notion, Airtable, or your CRM instead of Sheets.
How you can use or extend it
-
Connect with Slack or email so contacts are instantly shared with your sales team.
-
Send follow-up messages automatically after adding new leads.
-
Add data validation (e.g., check if an email already exists before saving).
-
Use tags or categories to group contacts by event or source.
