PDF to Structured JSON Without ML Training: A 2026 Developer Guide
The article discusses advancements in PDF extraction technology, particularly focusing on the transition from traditional methods to LLM-based solutions. It outlines the evolution of PDF processing from text extraction to complex layout handling using AI. Key insights include the importance of schema enforcement and the efficiency of page-by-page processing for improved accuracy.
- ▪The four eras of PDF extraction include text PDFs, scanned PDFs, layout-aware OCR, and LLM extraction.
- ▪Using a JSON schema ensures deterministic outputs and helps avoid issues like hallucinations in extracted data.
- ▪Processing PDFs page-by-page is more effective than whole-document approaches, especially for long contexts.
