Overview

The Syncfusion Smart Data Extractor is a high-performance C# library for .NET that extracts structured information from PDFs and scanned images. Using machine-learning–based layout analysis, it identifies document elements such as tables, form fields, and key content regions by analyzing visual patterns like lines, boxes, labels, and alignment. The library returns structured JSON with confidence scores for each extracted element, enabling reliable indexing, analytics, and automated data processing, and can optionally generate digitally reconstructed PDFs for validation and archival workflows.

Why choose the Syncfusion Smart Data Extractor?

Zero external AI dependencies

The extraction engine runs entirely within your .NET environment without requiring external AI services or cloud APIs. This allows organizations to process documents securely while maintaining full control over data privacy, legal and regulatory compliance, and operational costs.

High performance at scale

The extraction engine is optimized for large-scale document processing, enabling high-throughput extraction for batch workloads and real-time document pipelines. Efficient processing helps reduce operational overhead and improves processing turnaround time.

Fully offline .NET integration

Deploy the library directly within your application or on-premises infrastructure without any external runtime dependencies. This enables fully offline document processing, making it suitable for environments with strict data governance or security requirements.

Configurable extraction

Developers can configure extraction behavior to match different document formats by adjusting parameters such as page range, confidence score, and borderless table detection. These controls help improve extraction relevance and reduce false positives for specific document types.

Structured output formats

Extracted results can be exported as structured JSON for integration with downstream systems, analysis-ready JSON tables, or fillable PDFs that visually represent extracted structures for review and validation workflows.

Confidence-based validation

Machine learning models combined with layout-based analysis help identify document elements more reliably. Per-field and per-cell confidence scores allow applications to automate validation while minimizing manual correction.

Data extraction.

Extract data from PDF

The library extracts document structures such as hierarchies, text blocks, images, headers, and footers from PDFs and scanned images by analyzing visual layout patterns like lines, boxes, and alignment. It returns structured JSON with per-field confidence scores, enabling reliable indexing, metadata enrichment, and downstream ETL workflows. The engine can also generate digitally reconstructed PDFs to visually validate extracted results in automated processing pipelines.

Extract tables from PDFs

Table extraction identifies table regions, header rows, columns, and merged cells in PDFs and scanned documents using layout-aware analysis. Extracted tables are returned as analysis-ready JSON with preserved header relationships and per-cell confidence scores, making them easy to integrate into analytics, reporting, and business intelligence pipelines.

Table extraction.

Form recognizer.

Form recognizer for PDF

Form recognition detects form regions and extracts text fields, checkboxes, radio buttons, and signatures by interpreting visual patterns such as boxes and selection markers. The extracted results are returned as normalized JSON with confidence scores, enabling applications to automatically process form data. It can also generate fillable PDFs for validation and document review workflows.
