A Python-based system for extracting structured data from PDF documents into a strict JSON schema using layout-aware parsing.
- Layout-based extraction using PDF text coordinates
- No regex, no heuristic guessing
- Supports minor layout variations via configurable tolerance
- Strict JSON schema validation
- Built-in logging for traceability
- Modular and extensible design
The system relies on PDF text positions (x/y coordinates) to accurately map labels and values. This ensures reliable extraction even for complex or semi-structured PDFs such as invoices, reports, or statements.
