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.

Frequently Asked Questions

Docling generates a standardized hierarchical JSON schema containing document metadata, page bounds, semantic headings, body paragraphs, list structures, and tabular grids with cells, rows, and columns properly mapped.
Yes. Our Docling engine features integrated OCR. If your uploaded document contains scanned pages or photographs without an underlying digital text layer, the OCR pipeline detects and transcribes the text automatically into the resulting JSON.
Absolutely. Docling was engineered by IBM Research specifically for Retrieval-Augmented Generation (RAG) and document AI workflows, preserving document hierarchy and table layout far better than naive plain-text parsers.
Modifyle supports PDF files up to 250 MB for structured JSON conversion.
No. Files processed by our Docling worker are handled in ephemeral isolated sandboxes and permanently purged immediately after processing. Your documents are never stored or used to train machine learning models.
