Usage

In Angular import the library with: import {ExportToCSV} from "@molteni/export-csv";

Use the library:

Export only one specific columns

exportColumnsToCSV(JSONListItemsToPublish : any[], fileName : string, columns : string[]);

exporter = new ExportToCSV();
exporter.exportColumnsToCSV(this.blogArticles, "filename", ["title"])

exporter = new ExportToCSV();
objectToExport = [{column : 'äàü£™ , ®, ©,'}, {column: 'second row'}];
exporter.exportColumnsToCSV(objectToExport, "filename", ["column"])

Export all the columns

exportAllToCSV(JSONListItemsToPublish : any[], fileName : string);

var exporter = new ExportToCSV();
exporter.exportColumnsToCSV(this.blogArticles, "filename")

Configure the character to use as separator

By default the character ';' is used for the generation of the file. E.g.:

1;Test

If you need to generate the file with a different separator you can pass it as parameter, e.g.:

var exporter = new ExportToCSV();
exporter.exportColumnsToCSV(this.blogArticles, 'filename', {separator: ','});

The generated file will use the defined separator, e.g.:

1,Test
