Backup and delete workflows to Google Drive with n8n API and form trigger

🔍 Description: Effortlessly delete unused or inactive workflows from your n8n instance while automatically backing them up as .json files into your Google Drive. Keep your instance clean, fast, and organized — no more clutter slowing you down. This workflow is ideal for users managing large self-hosted n8n setups, or anyone who wants to maintain optimal performance while preserving full workflow backups.
