Document Formatting And Structure Preservation

via “document-to-markdown conversion with structure preservation”

IBM's document converter — PDFs, DOCX to structured markdown with OCR and table extraction.

Unique: Infers Markdown heading levels from visual hierarchy detected during layout analysis rather than using heuristics, producing semantically correct heading structures that reflect the original document's information hierarchy

vs others: More structure-aware than simple PDF-to-Markdown converters (Pandoc) because it uses layout analysis to infer heading levels; more flexible than fixed-template approaches because it adapts to variable document structures
