Syncfusion® .Net Core SmartFormRecognizer library

The Syncfusion® SmartFormRecognizer library is a deterministic C# library for .NET designed to accurately detect and interpret form data from PDFs and scanned images. By analyzing visual layout elements—such as lines, boxes and circles—it identifies structured form regions and extracts common field types including text inputs, checkboxes, radio buttons and signature areas. The library outputs clean, review-friendly JSON enriched with per‑field confidence scores. When form fields are successfully recognized, Smart Form Recognizer can also generate a corresponding fillable PDF, enabling immediate use and seamless integration into document workflows.

Key Features

  • Form layout detection: Locate form regions using graphical heuristics (lines, boxes, circles) for consistent field discovery.

  • Fillable PDF export: Create a PDF with detected form fields added so documents are immediately usable in form workflows.

  • Page-level control: Process specific pages or page ranges for targeted extraction.

  • Multi-format support: Works with PDF, JPEG, PNG and other common image formats.

  • Confidence filtering: Per-field confidence scores with configurable thresholds to control output quality and drive review logic.

  • Ready for .NET integration: Deterministic, on-premises library that outputs JSON and integrates into existing .NET pipelines and review UIs.

System Requirements

Getting started

  • You can fetch the Syncfusion® .NET Core SmartFromRecognizer library NuGet by simply running Install-Package Syncfusion.SmartFromRecognizer.Net.Core from the Package Manager Console in Visual Studio.

Detect Form Fields in PDFDocument programmatically using C#

// Open the input PDF file
FileStream inputStream = new FileStream("Input.pdf", FileMode.Open, FileAccess.Read);

// Create an instance of the Smart Form Recognizer
FormRecognizer recognizer = new FormRecognizer();

// Recognize the form and produce a PDF document with detected fields
PdfLoadedDocument pdfLoadedDocument = recognizer.RecognizeFormAsPdfDocument(inputStream);

// Save the resulting PDF to disk
pdfLoadedDocument.Save("Output.pdf");
