Answer 1

In case you use the new HttpClient class (@angular/common/http), then you will have to set the responseType to 'text', otherwise the HttpClient class would try to interpret the content as json and raise a SyntaxError...

e.g.:
this.http.get('assets/file.csv', {responseType: 'text'})
    .subscribe(
        data => {
            console.log(data);
        },
        error => {
            console.log(error);
        }
    );

I finally find a answer Here is how I done it:

csvUrl = 'assets/demo-Results.csv';
readCsvData () {
      this.http.get(this.csvUrl)
        .subscribe(
          data => {
            console.log(data.text())
          },
          err => {
            console.log(err)
          });
  }
