Get the JSON string for a JContainer:
JContainers_JSON.Serialize(containerId)
Or create a JContainer from a JSON string:
int containerId = JContainers_JSON.Parse("...")
With a shortcut for logging JContaines to the Papyrus log as JSON:
JContainers_JSON.Log(containerId)
JContainers_JSON.Log(containerId, "Optional Description")
