Installation

Start by installing the Angular Rich JSON CSV Parser library from npm

npm i -s ngx-rich-json-csv-parser

Next, you'll need to import the NgxRichJsonCsvParserModule module in your app's module.

app.module.ts

import { NgxRichJsonCsvParserModule } from 'ngx-rich-json-csv-parser';
...

@NgModule({
    ...
    imports: [NgxRichJsonCsvParserModule],
    ...
});

Next, To consume this library, create a instance of this library service in component ts file. eg csv-download-example.component.ts

import { Component } from '@angular/core';
import { HeaderCaseMode, HeaderSortMode, NgxRichJsonCsvParserService } from 'ngx-rich-json-csv-parser';
...

export class CSVDownloadExampleComponent {

  jsonData = []; //your JSON data to convert CSV
  constructor(private _ngxRichJsonCsvParserService: NgxRichJsonCsvParserService) {

  }
  download() { // Sample function to covert JSON data to CSV and download CSV file 
    this._ngxRichJsonCsvParserService.downloadFile(this.jsonData, [], true, 'test', 'mySl', SortMode.DESC, HeaderCaseMode.StartCase);
  }
}

Usages and API details

To download JSON data as a CSV file format, use downloadFile() function, eg:

this._ngxRichJsonCsvParserService.downloadFile(<Your JSON Data>,<Custom Header List>,<show Serial Number(boolean)>,<Your CSV File Name>,< your Serial Number Header Name>, < Sort Header list>,<Format your CSV headers text cases> );

Argument Details

Order	Name	Type	Details
1	JSON Data	An array of objects	JSON data which is used to convert into CSV
2	Custom Header	An array of String	You can provide custom csv header name, please note number of element in this header array should be equal to number of property in single JSON array object data
3	isAutoGenerateSlNo(IsGenerateSerial Number)	Boolean	This flag is used to generate Numerical serial number start from 1
4	CSV File Name	string	Your custom CSV file name
5	Serial Number header name	string	If isAutoGenerateSlNo is true then you can provide custom header for Serial number
6	Sort CSV Header list	enum	To sort CSV Header list, available options are - without Sorting : HeaderSortMode.NONE - to sort ascending order: HeaderSortMode.ASC - to sort descending order: HeaderSortMode.DESC
7	Header Text format	enum	To format CSV all header text to uppercase or lowercase or capitalize or startcase(title case) eg: HeaderCaseMode.StartCase

this._ngxRichJsonCsvParserService.downloadFile(jsonData, [], true, 'test', 'mySl', SortMode.DESC, HeaderCaseMode.StartCase); //example

To convert JSON to CSV data format without downloading, use ConvertToCSV() function, eg:

this._ngxRichJsonCsvParserService.ConvertToCSV(this.jsonData, [], true, 'mySl', HeaderSortMode.DESC, HeaderCaseMode.StartCase); // this function returns csv data

console.log(c) //example
