Angular Material Table Exporter

Node version Total Downloads

This package is to make MatTable components exportable in excel, csv, txt and json formats. Pagination is also supported. Applying MatTableExporter directive to your MatTable is enough to make it exportable. The directive uses different exporter services for different exporting types. You can also implement your own exporter and use it for your custom exporting requirements.

This project employs xlsx sheetjs, which is a great library and mature enough for the excel creation itself. In order to achieve a cross-browser file saving capability FileSaverjs is employed.

The MatTableExporter directive inside this package is a cdk-table-exporter subtype and provides support for angular material's cdkTable. cdk-table-exporter facilitates the common exporting related functionalities for CdkTable implementations abstracting the behavior that can change among different CdkTables.


Getting Started

If you are employing angular material in your project. Install mat-table-exporter

npm install mat-table-exporter

npm install mat-table-exporter@1.2.5

For Angular versions between 8-13 (inclusive), please install mat-table-exporter@10.2.4

npm install mat-table-exporter@10.2.4

  imports: [



matTableExporter is the directive selector.

Bundle Size

Xlsx (sheetjs) is a core dependency of the package. Since it is built as a CommonJs module, proper tree-shaking is not available during the builds. That's why mat-table-exporter loads Xlsx dependencies dynamically since v10.2.3.

Even if Xlsx is loaded dynamically, it is heavy by nature. If you'd like to benefit the extra minified version of xlsx (; Doesn't support some features like .xls exporting) you can configure the module as shown below:

  imports: [
    MatTableExporterModule.forRoot({xlsxLightWeight: true}),


This project is a library project inside ng-material-extensions angular workspace. If you are interested in the source code of this particular library you can get ready and build the project by applying the steps below:

  1. Do npm install in ng-material-extensions directory
  2. Do npm install in ng-material-extensions\projects\cdk-table-exporter directory
  3. Do npm install in ng-material-extensions\projects\mat-table-exporter directory
  4. Go to ng-material-extensions directory
  5. Build both of the exporter packages:
ng build cdk-table-exporter
ng build mat-table-exporter
  1. You can run the showcase application and see your changes in action. In ng-material-extensions run ng s -o
