How do I fake compound/ nested data?

Hi
How do you create nested data such as below, as where I would want to bind it to (https://demos.telerik.com/kendo-ui/treeview/remote-data-binding) a tree view and I want to fake compound data.

{
                        "state": "Up",
                        "text": "BBC Partners Advisors LLP",
                        "items": [
                            {
                                "text": "UK",
                                "state": "Up",
                                "items": [
                                    {
                                        "text": "HQ House",
                                        "state": "Up",
                                        "items": [
                                            { "text": "acme-r_core_01" },
                                            { "text": "acme-sw_oslo_01" }
                                        ]
                                    }
                                ]
                            }
                        ]
                    },
