                    }
                ]
            },
            {
                "countryName": "Country 1",
                "FS": "15-JAN-2020",

                        "experience": 5
                    },
                    {
                        "countryId": 0,
                        "userId": "4",
                        "Username": "Smith",
                        "FI": "12-JAN-2020",

                        "experience": 5
                    },
                    {
                        "countryId": 0,
                        "userId": "4",
                        "Username": "Trumble",
                        "FI": "12-JAN-2020",
                        "LI": "21-Feb-2020",
                        "experience": 5
                    }
                ]
            }
        ]
    }

I am trying to access Username from getData Here is my ts code

const getUserData = this.dataService.getuserList().subscribe((data:any) => {
  console.log(data);
  this.reponsearray = data;   
  this.responseuserName = data.getData[0].Username;   
});

Here is my HTML

      <ng-container *ngFor="let item of responseuserName ">
           <th  [attr.colspan]="keycount" class="User-names">{{item.userName}}</th>
      </ng-container>

Please let me know what I am doing wrong here.

studyLevel array has desired data:

const getUserData = this.dataService.getuserList().subscribe((data:any) => {
  console.log(data);
  this.reponsearray = data;   
  this.responseuserName = data.studyLevel[0].getData[0].Username;   
});

UPDATE:

You can create a nested *ngFor:

<div *ngFor="let row of response.studyLevel">
  <div *ngFor="let col of row.getData">
    {{col.Username}} {{col.FI}} {{col.LI}}
  </div>
</div>

As a suggestion, you could rename responseuserName to responseuserNames.

The work stackblitz example can be seen here.

you can try like this. here as you can see we have an array of object the studyLevel and inside that we have another array of the object getData so we are using the two *ngFor loop one inside another

TS

const getUserData = this.dataService.getuserList().subscribe((data:any) => {
  console.log(data);
  this.responseuserName = data.studyLevel;   
});

HTML

 <ng-container *ngFor="let item of responseuserName ">
     <ng-container *ngFor="let data of intem. getData >
           <th  [attr.colspan]="keycount" class="User-names">
{{data.userName}}</th>
     </ng-container>
 </ng-container>
