SharePoint List Populator 2016
Using AngularJS, and SharePoint 2013 JSOM library, I created a simple company-internal tool to populate random but specifications-following per-field data for any SharePoint List. The app could figure out what rules of randomness could be set per field by reading the List definition, and propose a rule from an option set.
A small video of the app is available here https://drive.google.com/file/d/0BwC2DYNwkOy9akd1VTB5VVhjRUE/
