How to Change a PowerPoint Show (PPSX) to a Work File (PPTX)

PowerPoint files come in two formats: PPTX files are editable PowerPoint presentations, and PPSX files are a read-only format for presentations. You can edit a PPSX file, but first you need to convert it back to PPTX format.

Changing the file extension

Before trying anything else, it’s always worth seeing if you can just change the file extension. This sometimes works, although it depends on which version of Office you and your colleagues are using.

To change the file extension, right-click on the file and choose “Rename.”

Change the file extension (if it exists in the file name) from .ppsx to .pptx.

In our case, it didn’t work. The file always opens as a PPSX presentation. So, let’s go ahead and try another way.

Saving the file in PPTX format

PowerPoint can convert a PPSX file to a PPTX file. Here’s how.

First, open “PowerPoint” and choose File> Open to find the file you want to edit.

Go to File> Save As to save the file.

From the drop-down menu at the top right, choose “PowerPoint Presentation (* .pptx)” to save the file as an editable file that you can share with colleagues. Remember to click the “Save” button when you are done.
