body: <p>I am new to angular. I want to create a expandable tree in angular 5. I have tried to using Angular-tree-component and ngx-treeview. but the problem with them is they need a json in specif format.  is there any library which reads a any type of json and creates a expandable tree ? or do I need to convert my json in the format this npm modules will need it ?</p>
