Revit Key Schedule Data Export

Have you ever had a need to export all of your key schedule data? The sample code provided below was built for Revit 2015 and should upgrade just fine to newer versions if need be.

Since you cannot transfer updates to existing Key Schedules from one project to another, I needed a way to export the data to a standardized key schedule definition so that I could easily import that updated definition information to a new or existing key schedule in an external project. This sample code is what I am using to export all of my key schedules including all of their row data to json file.

No I will not make a Dynamo definition for this :)
