Excel exporting in Angular Grid component

18 Nov 202216 minutes to read

The excel export allows exporting Grid data to Excel document. You need to use the excelExport method for exporting. To enable Excel export in the grid, set the allowExcelExport as true.

To use excel export, inject ExcelExportService in the provider section of AppModule.

app.component.ts

import { Component, OnInit, ViewChild } from '@angular/core';
import { data } from './datasource';
import { GridComponent, ToolbarItems } from '@syncfusion/ej2-angular-grids';
import { ClickEventArgs } from '@syncfusion/ej2-angular-navigations';

@Component({
    selector: 'app-root',
    template: `<ejs-grid #grid id='Grid' [dataSource]='data' [toolbar]='toolbarOptions' height='272px'
               [allowExcelExport]='true' (toolbarClick)='toolbarClick($event)'>
                <e-columns>
                    <e-column field='OrderID' headerText='Order ID' textAlign='Right' width=120></e-column>
                    <e-column field='CustomerID' headerText='Customer ID' width=150></e-column>
                    <e-column field='ShipCity' headerText='Ship City' width=150></e-column>
                    <e-column field='ShipName' headerText='Ship Name' width=150></e-column>
                </e-columns>
                </ejs-grid>`
})
export class AppComponent implements OnInit {

    public data: object[];
    public toolbarOptions: ToolbarItems[];
    @ViewChild('grid') public grid: GridComponent;

    ngOnInit(): void {
        this.data = data;
        this.toolbarOptions = ['ExcelExport'];
    }

    toolbarClick(args: ClickEventArgs): void {
        if (args.item.id === 'Grid_excelexport') { // 'Grid_excelexport' -> Grid component id + _ + toolbar item name
            this.grid.excelExport();
        }
    }
}

app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { GridModule, ToolbarService, ExcelExportService, FilterService } from '@syncfusion/ej2-angular-grids';
import { AppComponent } from './app.component';

/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule,
        GridModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent],
    providers: [ExcelExportService, ToolbarService, FilterService]
})
export class AppModule { }

main.ts

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

Show spinner while exporting

You can show/ hide spinner component while exporting the grid using showSpinner/ hideSpinner methods. You can use toolbarClick event to show spinner before exporting and hide a spinner in the pdfExportComplete or excelExportComplete event after the exporting.

In the toolbarClick event, based on the parameter args.item.id as Grid_pdfexport or Grid_excelexport we can call the showSpinner method from grid instance.

In the pdfExportComplete or excelExportComplete event, We can call the hideSpinner method.

In the below demo, we have rendered the default spinner component when exporting the grid.

app.component.ts

import { Component, OnInit, ViewChild } from '@angular/core';
import { data } from './datasource';
import { GridComponent, ToolbarItems, ExcelExportService } from '@syncfusion/ej2-angular-grids';
import { ClickEventArgs } from '@syncfusion/ej2-angular-navigations';

@Component({
    selector: 'app-root',
    template: `<ejs-grid #grid id='Grid' [dataSource]='data' [allowPaging]='true'
    [toolbar]='toolbarOptions' height='272px' [allowPdfExport]='true' [allowExcelExport]='true'
    (excelExportComplete)='excelExportComplete()' (pdfExportComplete)='pdfExportComplete()'
    (toolbarClick)='toolbarClick($event)'>
                <e-columns>
                    <e-column field='OrderID' headerText='Order ID' textAlign='Right' width=120></e-column>
                    <e-column field='CustomerID' headerText='Customer ID' [visible]='false' width=150></e-column>
                    <e-column field='ShipCity' headerText='Ship City' width=150></e-column>
                    <e-column field='ShipCountry' headerText='ShipCountry' width=150></e-column>
                </e-columns>
                </ejs-grid>`,
    providers: [ExcelExportService]
})
export class AppComponent implements OnInit {

    public data: object[];
    public toolbarOptions: ToolbarItems[];
    @ViewChild('grid')  public grid: GridComponent;

    ngOnInit(): void {
        this.data = data;
        this.toolbarOptions = ['PdfExport', 'ExcelExport'];
    }

    toolbarClick(args: ClickEventArgs): void {
        if (args.item.id === 'Grid_pdfexport') {
            this.grid.showSpinner();
            this.grid.pdfExport();
        } else if (args.item.id === 'Grid_excelexport') {
            this.grid.showSpinner();
            this.grid.excelExport();
        }
    }

    pdfExportComplete(): void {
        this.grid.hideSpinner();
    }
    excelExportComplete(): void {
        this.grid.hideSpinner();
    }
}

app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { GridModule, ToolbarService, PdfExportService } from '@syncfusion/ej2-angular-grids';
import { AppComponent } from './app.component';

/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule,
        GridModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent],
    providers: [PdfExportService, ToolbarService]
})
export class AppModule { }

main.ts

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

Custom data source

The excel export provides an option to define datasource dynamically before exporting.
To export data dynamically, define the dataSource in excelExportProperties.

app.component.ts

import { Component, OnInit, ViewChild } from '@angular/core';
import { data } from './datasource';
import { GridComponent, ToolbarItems, ExcelExportProperties } from '@syncfusion/ej2-angular-grids';
import { ClickEventArgs } from '@syncfusion/ej2-angular-navigations';

@Component({
    selector: 'app-root',
    template: `<ejs-grid #grid id='Grid' [dataSource]='data' [toolbar]='toolbarOptions' height='272px'
               [allowExcelExport]='true' (toolbarClick)='toolbarClick($event)'>
                <e-columns>
                    <e-column field='OrderID' headerText='Order ID' textAlign='Right' width=120></e-column>
                    <e-column field='CustomerID' headerText='Customer ID' width=150></e-column>
                    <e-column field='ShipCity' headerText='Ship City' width=150></e-column>
                    <e-column field='ShipName' headerText='Ship Name' width=150></e-column>
                </e-columns>
                </ejs-grid>`
})
export class AppComponent implements OnInit {

    public data: object[];
    public toolbarOptions: ToolbarItems[];
    @ViewChild('grid') public grid: GridComponent;

    ngOnInit(): void {
        this.data = data;
        this.toolbarOptions = ['ExcelExport'];
    }

    toolbarClick(args: ClickEventArgs): void {
        if (args.item.id === 'Grid_excelexport') { // 'Grid_excelexport' -> Grid component id + _ + toolbar item name
            const excelExportProperties: ExcelExportProperties = {
                dataSource: data
            };
            this.grid.excelExport(excelExportProperties);
        }
    }
}

app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { GridModule, ToolbarService, ExcelExportService, FilterService } from '@syncfusion/ej2-angular-grids';
import { AppComponent } from './app.component';

/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule,
        GridModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent],
    providers: [ExcelExportService, ToolbarService, FilterService]
})
export class AppModule { }

main.ts

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

Passing additional parameters to the server when exporting

You can pass the additional parameter in the query property by invoking addParams method. In the toolbarClick event, you can define params as key and value pair so it will receive at the server side when exporting.

In the below example, we have passed recordcount as 12 using addParams method

app.component.ts

import { Component, OnInit, ViewChild } from '@angular/core';
import { data } from './datasource';
import { GridComponent, ToolbarItems, ToolbarService, PdfExportService, ExcelExportService } from '@syncfusion/ej2-angular-grids';
import { ClickEventArgs } from '@syncfusion/ej2-angular-navigations';
import { Query } from '@syncfusion/ej2-data';

@Component({
    selector: 'app-root',
    template: `<ejs-grid #grid id='Grid' [dataSource]='data' [allowPaging]='true'
    [toolbar]='toolbarOptions' height='272px' [allowPdfExport]='true' [allowExcelExport]='true'
    (excelExportComplete)='excelExportComplete()' (pdfExportComplete)='pdfExportComplete()'
    (toolbarClick)='toolbarClick($event)'>
                <e-columns>
                    <e-column field='OrderID' headerText='Order ID' textAlign='Right' width=120></e-column>
                    <e-column field='CustomerID' headerText='Customer ID' [visible]='false' width=150></e-column>
                    <e-column field='ShipCity' headerText='Ship City' width=150></e-column>
                    <e-column field='ShipCountry' headerText='ShipCountry' width=150></e-column>
                </e-columns>
                </ejs-grid>`,
    providers: [ToolbarService, PdfExportService, ExcelExportService]
})
export class AppComponent implements OnInit {

    public data: object[];
    public toolbarOptions: ToolbarItems[];
    @ViewChild('grid') public grid: GridComponent;
    public queryClone: any;

    ngOnInit(): void {
        this.data = data;
        this.toolbarOptions = ['PdfExport', 'ExcelExport'];
    }

    toolbarClick(args: ClickEventArgs): void {
        if (args.item.id === 'Grid_pdfexport') {
            this.queryClone = this.grid.query;
            this.grid.query = new Query().addParams('recordcount', '12');
            this.grid.pdfExport();
        } else if (args.item.id === 'Grid_excelexport') {
            this.queryClone = this.grid.query;
            this.grid.query = new Query().addParams('recordcount', '12');
            this.grid.excelExport();
        }
    }

    pdfExportComplete(): void {
        this.grid.query = this.queryClone;
    }
    excelExportComplete(): void {
        this.grid.query = this.queryClone;
    }
}

app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { GridModule, ToolbarService, PdfExportService } from '@syncfusion/ej2-angular-grids';
import { AppComponent } from './app.component';

/**

        BrowserModule,
        GridModule
    ],
    declarations: [AppComponent],

})
export class AppModule { }
