One Prompt That Turns PDF Slides Into Editable PPTX
Native text boxes only, python-pptx footguns encoded, self-verify against the original — five for five in my tests.
Sometimes you inherit a PDF deck and only need to change a few lines. I folded my personal slide-harness rules into one prompt that rebuilds editable PPTX via python-pptx for ChatGPT and Claude.
- Native elements only — TextBoxes and real Shapes; ban image-of-text, SmartArt hacks, random SVG dumps. Editability is the point.
- Encode python-pptx traps — proper dash styles, CJK font slots (ea/eastAsia/latin), right padding, exact HEX from source.
- Self-verify loop — render beside original up to three passes; fix only visible errors so pixel OCD does not wreck layout. Dashed lines may look broken in PNG previews but fine in PowerPoint — teach the model that.
Five tests, five usable outputs. Not pixel-identical art — editable working files.
