Thanks for getting Hype!
The JSON animation data is exported in the *_hype_generated_script.js file as part of a standard (“Folder”) export. This is meant to be used by Hype’s runtime and probably isn’t too useful for sharing or even being human readable. We also reserve the right to change this format in future releases.
I have field a to-do item to look into what kind of JSON Lottie requires since that might make an interesting new export option.
