We have found 4 software records in our database eligible for .pptm to .odp file format conversion.
pptm to odp conversion is simply a matter of export between two different presentation formats, from Microsoft PowerPoint's PPTM format to OpenDocument ODP format. The easiest way would be to simply resave the presentation with PowerPoint, but it is likely that the presentation tools from OpenDocument based productivity suites (OpenOffice/LibreOffice) can be used for the same thing.
