Python Docx

Overview

Python-docx is a Python library for creating and manipulating Microsoft Word (.docx) documents. This skill covers comprehensive patterns for document automation including:

• Document creation from scratch or templates
• Paragraph formatting with styles, fonts, and alignment
• Table generation with merged cells, styles, and formatting
• Headers and footers with page numbers and dynamic content
• Image insertion with sizing and positioning
• Style management for consistent document appearance
• Template manipulation for document workflows
• Mail merge patterns for bulk document generation

When to Use This Skill

USE when:

• Creating Word documents programmatically from data
• Generating reports with consistent formatting
• Building contracts, invoices, or legal documents
• Automating template-based document creation
• Modifying existing Word documents
• Creating documents with complex table structures
• Generating technical documentation with code blocks
• Building multi-section documents with headers/footers
• Creating documents with embedded images and charts
• Batch processing document generation

DON'T USE when:

• Simple template filling (use docx-templates instead)
• PDF generation is the final output (use pypdf or reportlab)
• Need real-time collaborative editing
• Document requires complex macros or VBA
• Need to preserve complex Word features (use COM automation on Windows)
• Only need to extract text from documents (use python-docx2txt)
