1. You need to set the response-header { responseType: 'blob'} in the request.

2. You need to pass in the correct MIME-Type as you'are creating the blob-file. (f.e. application/octet-stream or application/vnd.openxmlformats-officedocument.spreadsheetml.sheet).

component.ts

  const blob = new Blob([data], { type: 'application/octet-stream' });
  const url= window.URL.createObjectURL(blob);
  window.open(url);
}
