Extract business card contacts with LDX hub Gemini AnalyzeDoc and Google Sheets

Description

Quick overview
This workflow collects a business card photo/scan through an n8n form, uses LDX hub AnalyzeDoc (Gemini) to extract contact details as structured JSON, and appends the resulting fields as a new row in Google Sheets.

How it works
Receives a business card file upload (PDF/JPG/PNG) through an n8n form submission.
Sends the uploaded file to LDX hub AnalyzeDoc using the Gemini model and a fixed schema prompt to extract contact fields as JSON.
Parses the extracted JSON into individual fields like name, company, email, phone numbers, and address.
Appends the extracted fields as a single new row in the selected Google Sheets worksheet.

Setup
Install the community node n8n-nodes-ldxhub and add an LDXhub API credential with your API key.
Add a Google Sheets OAuth2 credential and select the target spreadsheet and worksheet in the append step.
Create (or match) a header row in your sheet for full_name, job_title, company, department, email, phone, mobile, address, website, notes so the auto-mapping writes to the correct columns.
