My expectations are low, mainly focused on using a compare tool to identify that there is a change and locating where that is so I can review it manually and decide how to sync up the two versions. In that sense a compare of sorted JSON text (including sorted arrays (lists) of objects (dicts) - which normal semantic diff tools don't do) is drastically better at identifying real changes then is comparing JSON files as they are natively exported by Ignition. @nminchin I may need to review your compare script and elevate my expectations 🙂 I'm guessing your script assigns more significance to the 'name' key in determining if a tag is added/removed and that any tag name change would likely be detected as a tag removal and a tag addition (suppose I should look before guessing). @nminchin @pturmel, thanks for the dialog! I'll try to find some time to educate myself with respect to `java.util.TreeMap` and @nminchin's external [compare script](https://forum.inductiveautomation.com/t/json-compare-tool-for-views-and-tags/41163/5). --- _[View the full topic](https://forum.inductiveautomation.com/t/ign-4488-is-tags-compare-between-2-versions-of-the-project-impossible/51143)._
