Track n8n Workflow Changes with Compare Dataset & Google Sheets

This n8n workflow automates the tracking of changes across all workflows in an n8n instance. It runs on a daily schedule, fetches current workflow JSON data via the n8n node, and processes each workflow in a loop. For each one, it checks a designated Google Sheet for prior versions. New workflows get a baseline entry created, while existing ones trigger a subworkflow using the Compare Dataset tool to identify node and connection changes.

Results, including detailed diffs, are appended or updated in the Google Sheet, providing a historical audit trail. This is invaluable for teams collaborating on a shared instance, ensuring visibility into modifications without constant manual checks. It also supports monitoring client-managed instances for unauthorized or unexpected changes.

Benefits include time savings on manual audits, proactive notifications of edits, and easy customization like adding AI for change impact analysis. Use cases span dev teams tracking iterations, service providers overseeing client environments, and solo users maintaining workflow integrity over time. A sample Sheet is available for reference.
