Deep Document Layout & Table Extraction for Developers and Data Pipelines

How Docling AI turns unstructured PDF documents into machine-readable JSON

PDFs are visually rich for human readers, but extracting reliable structured data for database ingestion, API integrations, and Large Language Model (LLM) fine-tuning has historically been difficult due to fragmented text streams and complex multi-column layouts.

Modifyle's PDF to JSON converter uses IBM Research's MIT-licensed Docling framework, paired with EasyOCR and TableFormer models. It analyzes document geometry to reconstruct true heading hierarchies, extract nested tables, and output a validated JSON schema.

Whether you are processing financial earnings reports, academic research papers, or municipal documents, our tool produces clean, developer-ready data structures.
