There is a tool to load and export any Spine animations.

It has most of the features, but no Debug layer.
It can open all Spine files, except 2.x.
Allows you to save as PNG sequence or MOV.

For more information, Readme here:

If this tool has helped you, please give me a Star.
If you have any questions, please open an issue.
