in detail:
Components file looks like below code –
import { Component, OnInit } from '@angular/core';
import { AngularCsv } from 'angular7-csv/dist/Angular-csv'
@Component({
selector: 'app-customer',
templateUrl: './customer.component.html',
styleUrls: ['./customer.component.css']
})
export class CustomerComponent implements OnInit {
constructor() { }
dtHolidays :any;
csvOptions = {
fieldSeparator: ',',
quoteStrings: '"',
decimalseparator: '.',
showLabels: true,
showTitle: true,
title: 'Your Holiday List :',
useBom: true,
noDownload: false,
headers: ["Holiday ID", "Holiday Date", "Holiday
Comment", "Holiday Status"]
};
ngOnInit() {
//Your data for download in csv file.
this.dtHolidays =[
{"id": 101, "Holiday_Date": "21/02/2019", "Holiday_Comment": "company holiday calendar of 2019. ", "Holiday_Status": "Active"},
{"id": 102, "Holiday_Date": "22/02/2019", "Holiday_Comment": "company holiday calendar of 2019.", "Holiday_Status": "Active"},

{"id": 104, "Holiday_Date": "24/02/2019", "Holiday_Comment": "company holiday calendar of 2019.", "Holiday_Status": "Active"},
{"id": 105, "Holiday_Date": "25/02/2019", "Holiday_Comment": "company holiday calendar of 2019.", "Holiday_Status": "NotActive"},
{"id": 106, "Holiday_Date": "26/02/2019", "Holiday_Comment": "company holiday calendar of 2019.", "Holiday_Status": "Active"},

];
}
downloadCSV(){
//this.dtHolidays : JSONDATA , HolidayList : CSV file Name,
this.csvOptions : file options
new AngularCsv(this.dtHolidays, "HolidayList", this.csvOptions);
}
}
And
<button (click)="downloadCSV()" class="btn-default">Download CSV</button>
An option looks like this.
filename: string;
fieldSeparator: string; //Defines the field separator character
quoteStrings: string;//If provided, will use this characters to "escape"
fields, otherwise will use double quotes as deafult
decimalseparator: string;//Defines the decimal separator character (default is .)
showLabels: boolean;//If provided, would use this attribute to create a header row
showTitle: boolean;
title: string;
useBom: boolean;//If true, adds a BOM
character at the start of the CSV
headers: string[];
noDownload: boolean; //If true, disables
automatic download and returns only formatted CSV
CsvConfigConsts looks like this.
static EOL: string;
static BOM: string;
static DEFAULT_FIELD_SEPARATOR: string;
static DEFAULT_DECIMAL_SEPARATOR: string;
static DEFAULT_QUOTE: string;
static DEFAULT_SHOW_TITLE: boolean;
static DEFAULT_TITLE: string;
static DEFAULT_FILENAME: string;
static DEFAULT_SHOW_LABELS: boolean;
static DEFAULT_USE_BOM: boolean;
static DEFAULT_HEADER: any[];
static DEFAULT_NO_DOWNLOAD: boolean;
AngularCsv class looks like this.
{
fileName: string;
labels: Array<String>;
data: any[];
private _options;
private csv;
constructor(DataJSON: any, filename: string, options?: any);
/**
* Generate and Download Csv
*/
private generateCsv;
/**
* Create Headers
*/
getHeaders(): void;
/**
* Create Body
*/
getBody(): void;
/**
* Format Data
* @param {any} data
*/
formartData(data: any): any;
/**
* Check if is Float
* @param {any} input
*/
static isFloat(input: any): boolean;
}
