Frequently Asked Questions

Which Python library is best for PDF table extraction?

The best library depends on your specific needs: Camelot excels at lattice-based tables, Tabula-py handles stream tables well, pdfplumber offers fine control, and PyMuPDF provides speed. Test multiple libraries on your specific PDF types.

Can these libraries extract tables from scanned PDFs?

Most libraries work only on digital PDFs. For scanned documents, you need to preprocess with OCR tools like Tesseract or use specialized solutions that combine OCR with table detection.

How do I handle tables spanning multiple pages?

Libraries like Camelot and pdfplumber offer page range parameters. You may need to process pages individually and concatenate results, or use advanced parameters to detect split tables across pages.

What's the typical accuracy for Python PDF table extraction?

Accuracy varies from 60-95% depending on PDF quality and table structure. Well-formatted digital PDFs with clear borders achieve higher accuracy than complex layouts or scanned documents.
