Syncfusion XlsIO is a .NET Excel library used to create, read, edit and convert Excel documents programmatically without Microsoft Excel or interop dependencies. Using this library, you can convert an Excel document to PDF in WPF.

Steps to convert an Excel document to PDF in WPF

Step 1: Create a new WPF application project.

Step 2: Name the project, choose the framework and click Create button.

Step 3: Install the Syncfusion.ExcelToPdfConverter.Wpf NuGet package as a reference to your project 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 applications to use our components.

Step 4: Add a new button in MainWindow.xaml as shown below.

C#

<Button Click="btnConvert_Click" Margin="0,0,10,12" VerticalAlignment="Bottom" Height="30" BorderBrush="LightBlue" HorizontalAlignment="Right" Width="180">
    <Button.Background>
        <LinearGradientBrush EndPoint="0.5,-0.04" StartPoint="0.5,1.04">
            <GradientStop Color="#FFD9E9F7" Offset="0"/>
            <GradientStop Color="#FFEFF8FF" Offset="1"/>
        </LinearGradientBrush>
    </Button.Background>
    <StackPanel Orientation="Horizontal" Height="23" Margin="0,0,0,-2.52" VerticalAlignment="Bottom" HorizontalAlignment="Right" Width="100">
        <Image Name="image2" Margin="2" HorizontalAlignment="Center" VerticalAlignment="Center" />
        <TextBlock Text="Convert Excel to PDF" Height="15.96" Width="126" Margin="0,4,0,3"/>
    </StackPanel>
</Button>

Step 5: Include the following namespaces in the MainWindow.xaml.cs.

C#

using Syncfusion.XlsIO;
using Syncfusion.Pdf;
using Syncfusion.ExcelToPdfConverter;

Step 6: Include the below code snippet in btnConvert_Click to convert an Excel document to PDF.

C#

using (ExcelEngine excelEngine = new ExcelEngine())
{
  IApplication application = excelEngine.Excel;
  application.DefaultVersion = ExcelVersion.Xlsx;
  FileStream excelStream = new FileStream("Sample.xlsx", FileMode.Open, FileAccess.Read);
  IWorkbook workbook = application.Workbooks.Open(excelStream);

  //Initialize ExcelToPdfConverter
  ExcelToPdfConverter converter = new ExcelToPdfConverter(workbook);

  //Initialize PDF document
  PdfDocument pdfDocument = new PdfDocument();

  //Convert Excel document into PDF document
  pdfDocument = converter.Convert();

  //Save the converted PDF document
  pdfDocument.Save("Sample.pdf");
}
