Introduction
Docling is an open-source Python library from the docling-project that revolutionizes how documents are prepared for generative AI. It provides robust capabilities for parsing and understanding a wide array of document formats, from standard PDFs and Office files to HTML, Markdown, and even audio. Docling aims to simplify the complex task of extracting structured information from unstructured and semi-structured documents, making it readily consumable by AI models and applications. Its advanced features include sophisticated PDF layout analysis, table structure recognition, and support for various export formats, ensuring data integrity and usability.
Installation
Getting started with Docling is straightforward. You can install it using pip:
pip install docling
Please note that Docling requires Python 3.10 or higher. It is compatible with macOS, Linux, and Windows environments, supporting both x86_64 and arm64 architectures. For more detailed instructions, refer to the official documentation.
Examples
Docling offers both a Python API and a convenient command-line interface (CLI) for document conversion.
Python API Example:
To convert individual documents programmatically:
from docling.document_converter import DocumentConverter
source = "https://arxiv.org/pdf/2408.09869" # document per local path or URL
converter = DocumentConverter()
result = converter.convert(source)
print(result.document.export_to_markdown()) # output: "## Docling Technical Report[...]"
CLI Example:
You can also convert documents directly from your terminal:
docling https://arxiv.org/pdf/2206.01062
Docling CLI also supports Visual Language Models (VLMs) like GraniteDocling:
docling --pipeline vlm --vlm-model granite_docling https://arxiv.org/pdf/2206.01062
