Table Extraction from PDF
A Practical Guide for Data Scientists and Researchers
Why PDFs Are Hard (and What That Means)
PDFs aren’t data files—they’re layout documents. Tables lack a true “row” or “column” structure, so tools must infer it. Visual differences, merged cells, and decorative lines often confuse parsers, especially across different sources or scanned images.
How Table Extraction Works
Classify each file (digital vs. scanned), preprocess, detect tables (lattice or stream), extract text, validate structure, and export clean CSV/XLSX files. Use heuristics for consistency, ML models for complex layouts, or hybrids for the best of both.
