# Automatically track n8n workflow changes and log to Google Sheets
This automation systematically captures structural changes in your n8n workflows—nodes and connections added, removed, or modified—and stores the full history in Google Sheets. Enables audit trails, version control, and change transparency without manual backup analysis. Ideal for administrators, DevOps teams, and organizations using n8n in shared environments.
