  "note": "Converting PPTX to PPT changes the presentation from the modern Office Open XML format to the older binary PowerPoint format. Some newer features such as advanced animations, SmartArt styles, embedded videos, and certain transitions may be simplified or lost, as they are not fully supported in the legacy PPT format. The conversion is ideal for ensuring compatibility with older versions of Microsoft Office and other software that cannot open PPTX files.",
