Question After effect to Unity

I created a 2D animation from After effect and export that as a Json file, and I want this Json file to Unity.
How can I do it? Is it need a plug in or something more.
Thanks for the help.

 

After Affects animations are not supported by Unity3D "as is", so you definitely have to use a plugin or write an animation parser yourself. I think the quickest way is to look at this or this plugin from the asset store. They are both paid. Maybe you can find some free plugins also.
