The Syncfusion^® Smart Data Extractor is a .NET library used to extract structured data and document elements from PDFs and images in WPF applications.

Steps to Extract Data from PDF document in WPF

Step 1: Create a new WPF application project.

In the project configuration window, name your project and select Create.

Step 2: Install the Syncfusion.SmartDataExtractor.WPF NuGet package as a reference to your WPF application NuGet.org.

Step 3: Include the following namespaces in the MainWindow.xaml.cs file.

C#

using System;
using System.IO;
using System.Text;
using System.Windows;
using Syncfusion.SmartDataExtractor;

Step 4: Add a new button in MainWindow.xaml to extract data from a PDF document as follows.

C#

<Grid>
    <Button Content="Extract Data"
            Width="150" Height="40"
            HorizontalAlignment="Center"
            VerticalAlignment="Center"
            Click="ExtractButton_Click"/>
</Grid>

Step 5: Add the following code in ExtractButton_Click to extract data from a PDF document using the ExtractDataAsJson method in the DataExtractor class. The extracted content will be saved as a JSON file

C#

// Open the input PDF file as a stream.
using (FileStream stream = new FileStream("Input.pdf", FileMode.Open, FileAccess.Read))
{
    // Initialize the Data Extractor.
    DataExtractor extractor = new DataExtractor();
    // Extract form data as JSON.
    string data = extractor.ExtractDataAsJson(stream);
    // Save the extracted JSON data into an output file (inline path).
    File.WriteAllText("Output.json", data, Encoding.UTF8);
}

A complete working sample can be downloaded from GitHub.

By executing the program, you will get the JSON file as follows.
