Vue Common - Utils - excelExporter

An object that serves as a namespace for the methods that export DevExtreme UI components to Excel.

exportDataGrid(options)

Exports grid data to Excel.

import { exportDataGrid } from "devextreme/excel_exporter"
Parameters:
options:

ExcelExportDataGridProps

Export settings.

Return Value:

Promise<CellRange> (jQuery or native)

A Promise that is resolved with an object that contains the coordinates of the first and last cells.

This method requires ExcelJS v4+ to export data and FileSaver v2.0.2+ to save files. If you apply CSP rules, refer to the ExcelJS CSP Treats section to read more about potential vulnerabilities.

You can call this method at any point in your application. In the example below, this method is called in the onExporting function that is executed before data is exported. As a result, the DataGrid is exported to a single worksheet.

JavaScript
HTML
$('#gridContainer').dxDataGrid({
    export: {
        enabled: true
    },
    onExporting: function(e) { 
        const workbook = new ExcelJS.Workbook(); 
        const worksheet = workbook.addWorksheet('Main sheet'); 

        DevExpress.excelExporter.exportDataGrid({ 
            worksheet: worksheet, 
            component: e.component 
        }).then(function() {
            workbook.xlsx.writeBuffer().then(function(buffer) {
