FAQPage Schema

How do I create a new PowerPoint presentation from scratch with python-pptx?▼

Instantiate a Presentation object, add slides using specific layout indices, then populate placeholders or text boxes with content. Use prs.slide_layouts to list available layouts, then set text via placeholders to preserve bullets and formatting.

How do I extract all text from a PowerPoint file?▼

Iterate through prs.slides, then through each shape's text_frame to collect paragraphs and runs. Extract speaker notes via slide.notes_slide.notes_text_frame. This gives you all text and formatting metadata without altering the original file.

Can I replace images in a PowerPoint deck without changing their size or position?▼

Yes, by locating the image's rId (relationship ID) in the underlying XML and overwriting the image part bytes directly. The replacement must use the same image encoding (PNG for PNG) to avoid file corruption.

What is the difference between editing text via placeholders versus text boxes?▼

Placeholders inherit layout-defined formatting (bullets, indentation, font) and are designed for slide templates, while text boxes are free-form. Always use placeholders for structured content to maintain design consistency.

Does python-pptx support converting .ppt legacy files?▼

python-pptx cannot directly open legacy .ppt files. Use LibreOffice (soffice) to convert .ppt to .pptx first, then process with python-pptx.

How do I export a PowerPoint presentation to PDF or images?▼

Use LibreOffice in headless mode via subprocess to convert .pptx to PDF, then pdftoppm to render slides as JPEG images. Both tools must be installed on the system; if unavailable, export is not possible.
