@Charlie-Funk Welcome!
The best option is to use OpenSCAD application.
JSCAD V1 (www.openjscad.org) supports a subset of the OpenSCAD functionality, and you can just drag and drog the file onto the lower white space (It says "Drag and drop file here...")
I hope that you have copy of the original .scad file. It's just a text file, so you can open and check the contents with various applications.
