I copied the code from this "tutorial":
https://sheetjs.com/demos/table.html
function doit(type, fn, dl) {
var elt = document.getElementById('data-table');
var wb = XLSX.utils.table_to_book(elt, {sheet:"Sheet JS"});
return dl ?
XLSX.write(wb, {bookType:type, bookSST:true, type: 'base64'}) :
XLSX.writeFile(wb, fn || ('test.' + (type || 'xlsx')));
}
So I ended up creating this method in Angular:
exportTableToExcel() {
var type = "xlsx"
var elt = document.getElementsByClassName('table');
var wb = XLSX.utils.table_to_book(elt, /*{sheet:"Sheet JS"}*/);
return XLSX.writeFile(wb, undefined || ('test.' + (type || 'xlsx')));
}
Well, on the line of the table_to_book method, I receive this exception:
table.getElementsByTagName is not a function
I also tried this tutorial, which is similar, but it's for Angular 4, not 5.

Mixing Jquery with Angular is not Recommened you can use ViewChild in Angular to Access DOM Element
you can access native DOM elements that have a template reference variable.
Example
HTML
<div class="container">
<table class="table" #table>
//....................
Component
import {Component,ViewChild, ElementRef} from '@angular/core';
import * as XLSX from 'xlsx';
export class AppComponent {
@ViewChild('table') table: ElementRef;
ExportToExcel()
{
const ws: XLSX.WorkSheet=XLSX.utils.table_to_sheet(this.table.nativeElement);
const wb: XLSX.WorkBook = XLSX.utils.book_new();
XLSX.utils.book_append_sheet(wb, ws, 'Sheet1');
/* save to file */
XLSX.writeFile(wb, 'SheetJS.xlsx');
}
}
