Document Processing

If you're building anything that touches office documents, this covers the practical stuff: extracting tables from PDFs with pdfplumber, writing Excel formulas (not hardcoded values) with openpyxl, pulling text from Word docs, and manipulating PowerPoint slides. The guide is heavy on tables showing which tool to use for what, plus important details like how XLSX/DOCX/PPTX are just ZIP files with XML inside, and why you should use tracked changes XML for legal documents instead of direct text replacement. It won't teach you document format internals, but it will point you to the right library and warn you about common mistakes like breaking Excel models by writing static values instead of formulas.
