"note": "PPTX is the modern Office Open XML format that supports better compression, improved interoperability, and enhanced multimedia capabilities compared to the older binary PPT format. Converting from PPT to PPTX will retain most content, but older transition effects, embedded OLE objects, or macros may behave differently. Slide layouts may be slightly altered if the original template is unavailable in the modern format.",
