It would be great to have a little bit of meta data included in the JSON exports so I can quickly validate that the JSON file being imported is in fact Spine data. Also maybe the version of Spine it was created with.
example of TexturePacker's meta block:
"meta": {
"app": "http://www.texturepacker.com",
"version": "1.0",
"image": "DudeCell.png",
"format": "RGBA8888",
"size": {"w":512,"h":1024},
"scale": "0.5",
"smartupdate": "$TexturePacker:SmartUpdate:1a3e06660e6f9855aca66037128ecde4$"
}
(note they also have a hash to determine whether anything has changed and needs to be updated)
Can't attach *.cs files apparently... but here ya go.
