I cannot find any conversions to JSON in the menus. I had attached the XML file (commentTest.x3d) to the previous message hoping that someone would be able to convert it. Perhaps there is not a tool for conversion at this time?

That version is from 13 February 2013.  There have been 2 or 3 occasions over the years where significant changes trip up the auto-updater.  Typical update rate is every 2-3 weeks.

The latest X3D-Edit includes .x3d to JSON conversion using the stylesheet.

Several annotated examples have been excerpted on the X3D to JSON Stylesheet page. More will be added.

All of the 3000+ examples (except for some deliberately erroneous test files) have been converted.

	http://www.web3d.org/x3d/content/examples/X3dResources.html#Examples

These have all been collected as a single zip to facilitate testing, with an error log to assist debugging.

	http://www.web3d.org/x3d/content/examples/build.json.out

John's recent release shows many of these examples getting loaded and displayed side by side in X3DOM and Cobweb.  Screenshots attached.

Your example scene commentTest.x3d and commentTest.json are attached.

all the best, Don
