Extract data from PDF forms

GroupDocs.Parser allows to parse form data from PDF documents.

To extract PDF form data please call the ParseForm method:

DocumentData ParseForm()

This method returns an instance of DocumentData class with the extracted data.

Here are the steps to parse form of the document:

  • Instantiate Parser object for the initial document
  • Call ParseForm method and obtain the DocumentData object;
  • Check if data isn’t null (parse form is supported for the document);
  • Iterate over field data to obtain form data.

The following example shows how to parse a form of the document:

// Create an instance of Parser class
using (Parser parser = new Parser(filePath))
{
    // Extract data from PDF document
    DocumentData data = parser.ParseForm();
    // Check if form extraction is supported
	if(data == null) {
		Console.WriteLine("Form extraction isn't supported.");
		return;
    }
    // Iterate over extracted data
    for (int i = 0; i < data.Count; i++)
    {
        Console.Write(data[i].Name + ": ");
        PageTextArea area = data[i].PageArea as PageTextArea;
        Console.WriteLine(area == null ? "Not a template field" : area.Text);
    }
}
