LEADTOOLS supports loading all form fields from a PDF file. Due to the nature and complexity of PDF form fields, (especially the prevalent use of PDF files that contain many custom and user-defined fields), LEADTOOLS reads the data as is and sets it in PDFFormField without any modification. Refer to the PDF Form Fields Demo for an example of parsing data to generate a live, editable PDF file.
