What is Docling Parser

Docling parses PDF, DOCX, PPTX, HTML, and other formats into a rich unified representation including document layout, tables etc., making them ready for generative AI workflows like RAG. This integration provides Docling's capabilities via the DoclingLoader document loader.

Docling is an open-source document parsing library developed by IBM, designed to extract information from various document formats like PDFs, Word documents, and HTML. It excels at converting these documents into formats like Markdown and JSON, which are suitable for use in AI workflows like Retrieval Augmented Generation (RAG). Docling utilizes fine-tuned table and structure extractors, and also provides OCR (Optical Character Recognition) support, making it effective for handling scanned documents. 

Here's a more detailed breakdown:
