How to display message excel not identical on angular 7 when press but

Jun 19 2021 11:03 PM

I work on angular 7 app that compare excel file uploaded with schema file excel I have

I face issue I can't display Excel Not Identical when press button upload and excel Not identical

so if excel file not identical or not same file schema I have then

when press button upload display message Excel Not Identical that display on console log on ts

so How to do that please

What I have tried:

public uploadFile = (files) => {
 .subscribe(resp => {
  if (resp) {
    console.log('Excel is Identical');
 .subscribe((response: Blob) => saveAs(response, this.fileToUpload.name + '.xlsx'));

    .subscribe((response: Blob) => saveAs(response, this.fileToUpload.name  + '.zip'));

  } else {
    console.log('Excel Not Identical');

on component.html 

<button (click)="uploadFile(files)" class="btn btn-link" style="margin-right: 0px">
    <nb-icon icon="cloud-upload-outline"></nb-icon>
