Automate Exporting to PNG from Layer Groups

Hello All. 

I am creating versions of the same image with different data for a project.  

Each group has one set of the correct information and each group is different.  

How can I automate exporting each seperate layer group to its own png file?

Would also like each file name as the layer group name.

I have attached an example of what I am looking at.  

This file is a sample.  Some of the actual design files are over 50 layer groups.
