Run python -m markitdown presentation.pptx to extract all slide text into Markdown. For a visual overview, use the thumbnail.py script to generate a labeled grid of slide images, or unpack the file to inspect raw slide XML.

Unpack the .pptx with unpack.py, duplicate or delete slides via add_slide.py and the sldIdLst in presentation.xml, edit each slide's XML directly, then run clean.py and pack.py to produce a validated output file.

pptxgenjs generates .pptx files programmatically with support for text, shapes, images, tables, and charts. Install it with npm install -g pptxgenjs and define slides using inch-based coordinates on layouts like LAYOUT_16x9.

Common causes include using '#' prefixes on hex colors, encoding opacity in 8-character hex strings, negative shadow offsets, or reusing option objects across calls since pptxgenjs mutates them. Use 6-character hex colors and fresh option objects per call.

Convert the deck to PDF with LibreOffice (soffice), then to per-slide JPEGs with pdftoppm at 150 DPI. Inspect the images for overlapping elements, text overflow, low contrast, and inconsistent spacing, then fix and re-render affected slides.

No, manual copying misses notes references, Content_Types entries, and relationship IDs. Use add_slide.py, which duplicates the slide, strips stale notes relationships, registers content types, and prints the sldId element to insert.
