FAQPage Schema

How do I extract text from a .pptx file for content analysis?▼

Extracting text from a .pptx file involves using markitdown with pptx extras to read slide contents reliably. This workflow outputs the plain text from your presentation so you can summarize or reuse the content elsewhere.

Can I create new slide decks from scratch without an existing template?▼

Yes, you can create new slide decks from scratch using PptxGenJS when no template is available. This approach generates brand-new presentation files directly, bypassing the need to unpack and modify existing slide XML.

What is the best way to edit existing PowerPoint slides programmatically?▼

The best way to edit existing PowerPoint slides is through a template-based workflow that unpacks the deck, modifies the slide XML, and repacks it. This guided process ensures structured presentation manipulation while maintaining the original layout.

Do I need LibreOffice or Poppler to generate visual QA thumbnails for presentations?▼

Yes, generating visual QA thumbnails requires LibreOffice (soffice) and Poppler (pdftoppm) to produce slide-by-slide visual exports. These dependencies render the slides to images, helping you catch layout issues like overflow, spacing, and contrast problems.

Does this presentation design workflow support catching layout issues like text overflow?▼

Yes, the visual quality assurance step produces thumbnails and slide-by-slide visual exports specifically to catch layout issues. This allows you to identify overflow, spacing errors, contrast problems, and leftover elements in your presentation design.
