Invoice2data

Invoice2data is a high-performance Python library and CLI tool designed for the automated extraction of structured data from semi-structured PDF and image files. In the 2026 market, it stands as the gold standard for deterministic, cost-effective document processing where high accuracy is required without the latency or cost of Large Language Models. Its technical architecture relies on a modular template system (YAML/JSON) that uses regular expressions and structural anchors to pinpoint data fields like invoice numbers, VAT details, and line items. It supports a variety of OCR backends, including Tesseract, GOCR, and commercial APIs like Google Cloud Vision or Amazon Textract, allowing architects to balance cost and precision. The tool is particularly favored for its ability to handle 'known' invoice formats with 100% accuracy while providing a framework for community-driven template sharing. It is ideal for high-volume batch processing and integrates seamlessly into enterprise ERP pipelines via JSON/CSV exports or custom Python hooks. Its 2026 positioning emphasizes its role as a local-first, privacy-conscious alternative to SaaS-only extraction platforms, fitting perfectly into edge computing and secure on-premise workflows.
