Excel to KML - Styling Folder Hierarchy

I believe what you want to do is modify the kml_parent, kml_document, kml_id, and kml_name attributes. Each folder has to be created with a kml_parent unless it's the root folder.

kml_document = name of your KML file

kml_parent = folder containing feature

kml_id, kml_name = feature as displayed in tree

I have a screenshot sample attached. I was trying to sort of figure out the same thing. I created some random data and merged it with a point using a creator and featuremerger. You can ignore those, because your spreadsheet should work fine. All the kml_parent attributes should be unique. If a sub-flight is "1" then all the flight data that has the same sub-flight number will go in one folder in the first decade and year (I guess). I hope this helps you out.

That did the trick! This information definitely got me on the right track! Thank you for the posted answer!
