What can I do with the Json file that is generated with a PNG sequence?

Hello.

I'm an After Effects (AE) specialist and I been using character animator (CH) with great results. I tried Googling and searching forums but I stillhave no idea why CH delivers a Json file along with the PNG and WAV render option. Is there something I can do with it? I'm spit balling here, will it help me integrate characters into webpages in a similar way that PSD exports an HTML? Can I use it for camera data in AE? I have no idea.

Thanks.
