About docling
Get your documents ready for gen AI
Docling is an open-source Python library designed to seamlessly convert complex documents into AI-ready formats, making it an essential tool for developers and data scientists working with generative AI. It supports a wide range of file types including PDF, DOCX, PPTX, XLSX, and HTML, extracting not just plain text but also preserving critical structural elements like tables, headers, and layouts. This ensures high-quality, structured outputs in JSON, Markdown, or plain text, which are perfect for feeding into large language models (LLMs) or other AI pipelines. Unlike many basic converters, Docling excels at handling intricate document structures, turning messy PDFs into clean, analyzable data without losing context. Its free, GitHub-hosted nature encourages community collaboration and customization, offering a powerful, flexible solution for automating document preprocessing and enhancing AI application accuracy.
Common Use Cases
- Convert PDF reports to structured JSON for easy integration with AI data analysis tools.
- Extract tables and text from research papers to prepare datasets for machine learning training.
- Transform business documents like invoices or contracts into Markdown for summarization by LLMs.
- Parse PowerPoint presentations to extract slide content and notes for automated content generation.
- Process HTML web pages into clean text formats to feed into chatbots or search indexing systems.
