Create a simple Excel report
The below steps illustrates creating an simple Invoice formatted Excel document in UWP application.
- Create a new C# Blank App (Universal Windows) project.
- Install the Syncfusion.XlsIO.UWP NuGet package as reference to your .NET Framework applications from NuGet.org.
-
Add a new button in the MainPage.xaml as shown below.
<Page x:Class="GettingStarted_UWP.MainPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="using:GettingStarted_UWP" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" Background="{ThemeResource ApplicationPageBackgroundThemeBrush}"> <Grid> <Button x:Name="button" Content="Create Document" Click="OnButtonClicked" HorizontalAlignment="Center" VerticalAlignment="Center"/> </Grid> </Page>
-
Include the following namespaces in the MainPage.xaml.cs file.
using Syncfusion.XlsIO; using Windows.Storage.Pickers; using Windows.Storage; using Windows.UI;
Imports Syncfusion.XlsIO Imports Windows.Storage.Pickers Imports Windows.Storage Imports Windows.UI
-
Include the below code snippet in the click event of the button in MainPage.xaml.cs, to create an Excel file and save the Excel document as a physical file and open the file for viewing.

NOTE
Starting with v16.2.0.x, if you reference Syncfusion assemblies from trial setup or from the NuGet feed, you also have to add “Syncfusion.Licensing” assembly reference and include a license key in your projects. Please refer to this link to know about registering Syncfusion license key in your applications to use our components. You can also explore our UWP Excel library demo that shows how to create and modify Excel files from C# with just five lines of code.
