Frequently asked questions
Can I extract speaker notes with this tool?
Yes. Enabling the Include Speaker Notes option retrieves presenter notes stored within the slide XML structure.
Is my PowerPoint file uploaded to a server?
No. Extraction is performed locally in your browser memory using JavaScript XML parsing.
Does this tool support older .ppt files?
No. It only supports modern XML-based .pptx files. Convert legacy .ppt files to .pptx in PowerPoint before extracting.
Will images and charts be extracted?
This tool extracts text nodes, titles, bullet points, and speaker notes. Embedded images and graphic elements are not extracted.
