Syncfusion^® PowerPoint is a UWP PowerPoint library used to create, read, edit and convert PowerPoint documents programmatically without Microsoft PowerPoint or interop dependencies. Using this library, you can open and save a Presentation in UWP.

Steps to open and save PowerPoint Presentation programmatically

Step 1: Create a new C# UWP application project.

Step 2: Install the Syncfusion.Presentation.UWP NuGet package as reference to your .NET Standard applications from NuGet.org.

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 application to use our components.

Step 3: Add a new button in the MainPage.xaml as shown below.

C#

<Page
    x:Class="Read_and_edit_PowerPoint_presentation.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:Read_and_edit_PowerPoint_presentation"
    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="Open and Save Presentation" Click="OnButtonClicked" HorizontalAlignment="Center" VerticalAlignment="Center"/>
    </Grid>
</Page>

Step 4: Include the following namespaces in the MainPage.xaml.cs file.

C#

using Syncfusion.Presentation;

Step 5: Include the below code snippet in the click event of the button in MainPage.xaml.cs, to Open an existing PowerPoint Presentation in UWP.

C#

//"App" is the class of Portable project.
Assembly assembly = typeof(App).GetTypeInfo().Assembly;
//Open an existing PowerPoint presentation
IPresentation pptxDoc = Presentation.Open(assembly.GetManifestResourceStream("Read_and_edit_PowerPoint_presentation.Assets.Template.pptx"));

Step 6: Add below code snippet demonstrates accessing a shape from a slide and changing the text within it.

C#

//Gets the first slide from the PowerPoint presentation
ISlide slide = pptxDoc.Slides[0];
//Gets the first shape of the slide
IShape shape = slide.Shapes[0] as IShape;
//Change the text of the shape
if (shape.TextBody.Text == "Company History")
    shape.TextBody.Text = "Company Profile";

Step 7: Add below code snippet to Save and close the presentation.

C#

//Initializes FileSavePicker
FileSavePicker savePicker = new FileSavePicker();
savePicker.SuggestedStartLocation = PickerLocationId.Desktop;
savePicker.SuggestedFileName = "Result";
savePicker.FileTypeChoices.Add("PowerPoint Files", new List<string>() { ".pptx" });
//Creates a storage file from FileSavePicker
StorageFile storageFile = await savePicker.PickSaveFileAsync();
//Saves changes to the specified storage file
await pptxDoc.SaveAsync(storageFile);
//Close the PowerPoint presentation
pptxDoc.Close();

You can download a complete working sample from GitHub.
