PPSX files are PowerPoint slide shows that open directly to the presentation.
What Is a PPSX File?
A file with the PPSXfile extensionis a Microsoft PowerPoint slide show.
PowerPoint Save As options.
These files open directly to the presentation because they’re meant to be used just for presenting the slideshow.
PowerPoint files that open directly into the editing mode are saved with thePPTXextension.
PPSX files useXMLandZIPto organize and compress the different parts of the file, just like Microsoft’sDOCXandXLSXfile formats.
PowerPoint Save As options.
Your next best option is Microsoft’s freePowerPoint Viewerprogram.
It’s helpful if you just need to view the presentation and not do any editing.
Since presentation mode starts immediately, you could’t just double-click or double-tap the file to edit it with PowerPoint.
Instead, you have toopen PowerPoint first and then use the menu to browse for it.
Some of these formats may only be seen from anExportmenu, not the regularSave Asmenu.
For example, the GroupDocs online viewer supports exporting to PDF.
Use theFile>Save Asmenu for several other choices.
Afree file converteris another way you’re free to convert it to a different format.
For an offline option, we recommendFilestar.
It runs on Windows and macOS, and can save the PPSX file to dozens of other formats.
Still Can’t Open It?
Check that you’re not confusing it with a similar file extension.
PPX and PPP files, for example, are documents used with non-Microsoft software.
