pptx

To extract text from a PPTX file, the skill utilizes markitdown to pull slide content directly from the .pptx input. This extracted text is then ready for downstream tasks like generating summaries, emails, or indexing presentations.

The best way to edit slide XML is through an unpack → clean → pack OOXML workflow. This skill unpacks the PPTX structure, allows safe template-driven XML modifications, cleans unused parts, and repacks it into a valid output file.

To visually QA a slide deck, the skill converts slides into image thumbnails using LibreOffice and poppler. These generated images allow you to inspect and verify layouts against spacing issues, overlaps, and text overflow.

Yes, this PPTX editing workflow requires LibreOffice to be installed. It relies on LibreOffice and poppler tooling for PDF conversion and visual inspection, alongside Pillow and python scripts to handle the thumbnail generation process.

Yes, you can create new presentations from templates using unpacked OOXML. The skill supports template-driven creation by unpacking the PPTX, safely editing the slide XML, removing unused components, and packing a corrected .pptx output.

When manipulating PPTX files at the XML level, limitations include potential layout shifts that require visual QA loops to catch. The workflow mitigates this by generating visual thumbnails to verify that XML edits do not cause overflow or spacing issues.
