Can you provide some details on what you are wanting to do when iterating? If the keys of the objects in the array is what is changing, you can use Object.keys(obj) to get a list of the keys in the object which you can then loop over. — Daniel W Strimpel

If you want to keep both new and existing data from array, better you can store it somewhere in the local variable and iterate over it.

whenever new data comes push new data into existing array, like below -

fullData: Array<any> = [];

this.fullData.push({
      "2018": {
        "score": "0.03726378083229065",
        "TxnNo": "2293760_1-2019r",
        "month_interest_std": "23.632556357702818",
        "m4_last_payment_amount": "1031.94",
        "firstInstalmentDate": "2/28/2018",
        "m6_balance": "15044.57",
        "m2_m1_balance": "0.06796083071380637",
        "period_max": "24.0",
        "paymentmethod_nan": "0"
      })

<div *ngFor='let item of fullData'>{{item?.TxnNo}}</div>
