New Item Creation

So I am looking to create a new item in Foundry and then import one of Crymic’s .JSON files into the new item. After I right click the item and slect import data I get a pop-up box as expected but when I go to chose the .JSON file from my machine it just crashes and times out in Chrome. Is there another way I can import a .JSON file for just one specific item?

Specifically, I am trying to get the Channel Divinity: Twilight Sanctuary macro/automation to work. Thanks in advance for any help or direction!
