JSON GET parse array

I am developing a plan with JSON GET to get glossary’s comments on ONE. I can get columns like ‘id’, ‘entityId’, ‘content’, etc. , but how to get the comment’s glossary id. It is an array with name ‘"relatedEntityIds’, but I can not find a way to get the elements in array.
Anybody knows about it?
