DemoMacro

Generate, parse, and patch Office Open XML documents (.docx, .pptx, .xlsx) using pure JSON options and functional API. Use when creating Word documents, PowerPoint presentations, or Excel spreadsheets with TypeScript — paragraphs, tables, images, charts, shapes, math equations, headers, footers, styles, effects, animations, data validation, or exporting to buffer/blob/base64. Also use when parsing existing OOXML files or patching template placeholders. Do not use for PDF generation, CSV files, or non-Office document formats.
