Track n8n Workflow Changes Over Time with Compare Dataset Google Sheets

## Try It Out!
### This n8n template runs daily to track and report on any changes to available workflows on an n8n instance.

Useful if a team is working within a single instance and you want to be notified of what workflows have changed since you last visited them. Another use-case might be monitoring your managed instances for clients and being alerted when changes are made without your knowledge.

See a sample Gsheet here: [https://docs.google.com/spreadsheets/d/1dOHSfeE0W_qPyEWj5Zz0JBJm8Vrf_cWp-02OBrA_ZYc/edit?usp=sharing](https://docs.google.com/spreadsheets/d/1dOHSfeE0W_qPyEWj5Zz0JBJm8Vrf_cWp-02OBrA_ZYc/edit?usp=sharing)

### How it works
* A scheduled trigger is set to run once a day to review all available workflows.
* An n8n node imports the workflows as json.
* The workflows are brought into a loop where each is first checked to see if it exists in the designated google sheet.
* If not, a new entry is created and skipped.
* If the workflow has been captured before, then the comparison subworkflow can be executed using the previous and current versions of the workflow json data.
* The subworkflow uses the compare dataset tool to calculate the changes to nodes and connections for the given workflow.
* The results are then recorded back to the google sheet for review.

### How to use
* Start with the n8n node and try to filter by the workflows you're interested in tracking.
* Set the scheduled trigger interval to match the frequency to suit how often your workflows are being edited.
