How to Open a PowerPoint PPSX in Presentation Mode from SharePoint
Question details
Users need a PPSX file hosted on SharePoint to open directly into slideshow mode instead of the default editing or reading view.
- Product
- SharePoint / PowerPoint for the web
- Device & OS
- not provided
- Scenario
- Accessing and viewing a shared PPSX presentation file via a SharePoint link in a web browser.
- Observed behavior
- The PPSX file opens in editing mode in PowerPoint for the web rather than automatically launching the presentation slideshow.
Verify whether you are opening the file in a web browser using PowerPoint for the web or through a local desktop application, as web browsers handle auto-play presentation formats differently.
Download the PPSX File to Open Locally
Downloading the file ensures it opens correctly in presentation mode on your desktop, bypassing the web browser's limitations.
PowerPoint for the web does not currently support automatically launching PPSX files into slideshow mode. By downloading the file to your computer, your local presentation software will process the PPSX extension properly and start the slideshow immediately.
Navigate to the SharePoint document library where the PPSX file is stored.
Select the file and click on 'Download' from the top command bar or the context menu.
Locate the downloaded file on your computer and double-click it. It will automatically launch in presentation mode.
Manually Start Slide Show in PowerPoint for the Web
If you prefer not to download the file, you can manually trigger the presentation mode after the file opens in the browser.
Experience Flawless Presentations with WPS Office
If you frequently encounter limitations viewing files in web-based platforms, consider switching to WPS Office. It is a powerful, free, and lightweight Office suite that guarantees seamless playback for your presentations.
- 1. Download and Install: Visit the official WPS Office website to download and install the free software.
- 2. Open your Presentation: Double-click your downloaded PPSX file, and WPS Presentation will handle it perfectly.
- 3. Present with ease: Enjoy a distraction-free, professional presentation mode that works exactly as intended.
Frequently Asked Questions
What is the difference between a PPTX and a PPSX file?
A PPTX file is a standard PowerPoint presentation designed to open in editing mode. A PPSX file is a PowerPoint Show format specifically saved to open directly into presentation (slideshow) mode.
Can I force SharePoint to open a PPSX file directly into presentation mode?
Currently, you cannot force SharePoint to do this in the web browser. PowerPoint for the web does not natively support automatically launching PPSX files into presentation mode, defaulting instead to an editing or reading view.
Why does my PPSX file work perfectly on my computer but not on SharePoint?
Desktop presentation applications are designed to recognize the PPSX extension and trigger the slideshow automatically. Web-based viewers like PowerPoint for the web are optimized for collaborative editing and reading, which overrides the auto-show behavior.
