# Extract structured markdown, JSON, and tagged-PDF-ready outputs from PDFs with OpenDataLoader PDF

Convert PDFs into LLM-ready markdown or coordinate-aware JSON, and use the same pipeline for tagged-PDF accessibility workflows when that is the real job to be done.

## Prerequisites

Python 3.10+, Java 11+, PDF inputs, optional hybrid-mode backend setup for complex pages or OCR-heavy jobs

## Installation

Use the upstream install or setup path that matches your environment:
- pip install -U opendataloader-pdf
- npm install @opendataloader/pdf
- pip install -U "opendataloader-pdf[hybrid]"
- pip install -U langchain-opendataloader-pdf

Requirements and caveats from upstream:
- sdk: Python, Node.js, Java
- **Requires**: Java 11+ and Python 3.10+ ([Node.js](https://opendataloader.org/docs/quick-start-nodejs) | [Java](https://opendataloader.org/docs/quick-start-java) also available)
- python

Basic usage or getting-started notes:
- pricing: open-source core (data extraction, layout analysis, auto-tagging to Tagged PDF), enterprise add-on (PDF/UA export, accessibility studio)
- extraction-benchmark: #1 overall extraction accuracy (0.907) in hybrid mode, 0.928 table extraction accuracy, 0.015s/page local mode
- accessibility-validation: PDF Association collaboration, Well-Tagged PDF specification, veraPDF automated validation
