I came across an interesting demo on exporting data to Excel using Angular 12. The demo can be found at the following link:
This particular example utilizes an array within the component TypeScript file.
import { Component } from '@angular/core';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
title = 'excel';
ngOnInit() {
this.sales = [
{ brand: 'Apple', lastYearSale: '51%', thisYearSale: '40%', lastYearProfit: '$54,406.00', thisYearProfit: '$43,342' },
{ brand: 'Samsung', lastYearSale: '83%', thisYearSale: '96%', lastYearProfit: '$423,132', thisYearProfit: '$312,122' },
{ brand: 'Microsoft', lastYearSale: '38%', thisYearSale: '5%', lastYearProfit: '$12,321', thisYearProfit: '$8,500' },
{ brand: 'Philips', lastYearSale: '49%', thisYearSale: '22%', lastYearProfit: '$745,232', thisYearProfit: '$650,323,' },
{ brand: 'Song', lastYearSale: '17%', thisYearSale: '79%', lastYearProfit: '$643,242', thisYearProfit: '500,332' },
{ brand: 'LG', lastYearSale: '52%', thisYearSale: ' 65%', lastYearProfit: '$421,132', thisYearProfit: '$150,005' },
{ brand: 'Sharp', lastYearSale: '82%', thisYearSale: '12%', lastYearProfit: '$131,211', thisYearProfit: '$100,214' },
{ brand: 'Panasonic', lastYearSale: '44%', thisYearSale: '45%', lastYearProfit: '$66,442', thisYearProfit: '$53,322' },
{ brand: 'HTC', lastYearSale: '90%', thisYearSale: '56%', lastYearProfit: '$765,442', thisYearProfit: '$296,232' },
{ brand: 'Toshiba', lastYearSale: '75%', thisYearSale: '54%', lastYearProfit: '$21,212', thisYearProfit: '$12,533' }
];
}
However, I encountered an error indicating that the property 'sales' does not exist on type 'AppComponent'.
After researching the issue online, it appears that I might need to initialize the 'sales' property. But isn't it already initialized in the code?
