PDF files can be challenging to extract data from due to their complex structure. However, there are several tools and techniques that can be used for PDF data extraction, including:
PDF Scraping: This involves using web scraping tools to extract data from PDFs that are available online.
OCR: This involves using OCR tools to extract text from PDFs that are scanned or image-based.
PDF Parsing: This involves using PDF parsing libraries, such as PyPDF2 and PDFMiner, to extract data from PDFs programmatically.
