Auto-Save LINE Files to Google Drive with Sheets Logging

This n8n workflow captures file uploads via LINE Messaging API webhook, validates file types against a configurable allowlist from Google Sheets, and organizes files into date-based folders (with optional type subfolders) in Google Drive. It logs each upload with metadata like filename, date, URL, and type for auditing, then sends an instant LINE reply confirming success or rejecting disallowed types.

Benefits include hands-free file management, structured organization reducing manual sorting, comprehensive logging for compliance and analytics, and seamless user feedback enhancing LINE bot interactions. It saves hours of manual archiving for teams handling high-volume media from customers or students.

Ideal for businesses using LINE for customer support, marketing campaigns, or educational platforms collecting assignments/media. Developers can customize via Sheets config without code changes; IT admins gain scalable file ingestion with audit trails. No-code users automate LINE-Drive-Sheets integration effortlessly.
