How to set json file to object's array in Angular

how to set json file to my "Client" object's array? I have json, which looks like this:
Clients.json

{
   "clients": [
   {
      "firstName": "nameA",
      "lastName": "lastA",
      "doctorsName": "domm",
      "procedure": "consultation",
      "registrationDate": "new Date(2019, 10, 12)",
      "isAlreadyServed": "false"
   },
   {
      "firstName": "nameB",
      "lastName": "lastB",
      "doctorsName": "domm",
      "procedure": "procedureA",
      "registrationDate": "new Date(2019, 10, 12)",
      "isAlreadyServed": "false"
   },
   {
      "firstName": "nameC",
      "lastName": "lastC",
      "doctorsName": "doctorA",
      "procedure": "procedureC",
      "registrationDate": "new Date(2019, 10, 12)",
      "isAlreadyServed": "false"
   },

   ...
   ...
   ...

And how can I set it to object's array Client.service.ts

clients: Client[] = this.http.get('path.Clients.json') // ??
