After you install the 2007 Microsoft Office system Service Pack 2 (SP2), you can open and save files in the OpenDocument Presentation (.odp) file format used by some presentation applications, such as OpenOffice.org Impress and Google Docs.
What do you want to do?
Open an OpenDocument Presentation file in PowerPoint
Click the Microsoft Office Button , and then click Open.
In the File of type list, click OpenDocument Presentation.
Click the file you want to open, and then click Open
Note: When you open a OpenDocument Presentation file in PowerPoint 2007, it might not have the same formatting as it did in the original application it was created in. This is because of the differences between applications that use the OpenDocument Format.
Save a PowerPoint presentation in the OpenDocument Presentation format
Important: If you want to keep a PowerPoint version of your file you must first save the file as a PowerPoint document, for example in the .pptx file format, and then save it again in the OpenDocument Presentation (.odp) format.
Click the Microsoft Office Button , and click Save As.
Click OpenDocument Presentation.

When you open or save presentations in the OpenDocument Presentation (.odp) format, some formatting might be lost. This is because of the different features and options, such as formatting, that OpenDocument Presentation applications and PowerPoint 2007 support.
Before sending a file to someone else, you might want to close the file and open it again to see what it looks like in OpenDocument Presentation (.odp) format.
To keep advanced object formatting that is not supported in the OpenDocument Presentation format, convert the object to a picture.
When you work with tables, complete the table before closing PowerPoint 2007. Tables are converted to images when you close PowerPoint 2007 and cannot be subsequently edited.
Avoid using emphasis animations (that is, animations that are not entrance or exit animations) that involve color change or scaling because those parts of animations are lost when you save the presentation in the .odp file format.
