Create, edit, or analyze the contents of .pptx files when requested. A .pptx file is essentially a ZIP archive containing XML files and other resources. Different tools and workflows are available for different tasks.
Before starting any presentation task, read ALL relevant documentation files completely to understand the full workflow:
html2pptx.md and css.md in their entiretyooxml.md in its entiretycss.mdNEVER set any range limits when reading these files. Understanding the complete workflow, constraints, and best practices before starting is essential for producing high-quality presentations. Partial knowledge leads to errors, inconsistent styling, and visual defects that require rework.
To read just the text content of a presentation, convert the document to markdown:
# Convert document to markdown
python3 -m markitdown path-to-file.pptx
Use raw XML access for: comments, speaker notes, slide layouts, animations, design elements, and complex formatting. To access these features, unpack a presentation and read its raw XML contents.
python3 ooxml/scripts/unpack.py <office_file> <output_dir>
