import studentsData from './students.json';
  
interface Student {
    id: Number;
    name: String;
    email: String;
    gender: String;
}
  
@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: [ './app.component.css' ]
})
export class AppComponent  {
  name = 'Angular';
  
  students: Student[] = studentsData;

I used bootstrap class on this form. if you want to add than then follow this link too: Install Boorstrap 4 to Angular 9.

src/app/app.component.html

<div class="container">
  
  <h1>How to Display Data from Json File in Angular 9/8/7? - HDTuto.com</h1>
  
  <table class="table table-striped">
    <thead>
        <tr>
          <th>ID</th>
          <th>Name</th>
          <th>Email</th>
          <th>Gender</th>
        </tr>
    </thead>
    <tbody>
      <tr *ngFor="let student of students">
        <td>{{ student.id }}</td>
        <td>{{ student.name }}</td>
        <td>{{ student.email }}</td>
        <td>{{ student.gender }}</td>
      </tr>
