How to Open SPO Filesby Garrett Genet ; Updated September 15, 2017
IBM has developed a statistics program called Statistical Package for the Social Science (SPSS). It's designed to be used in academics, business, government and otherwise. If you work with statistics on a professional level then their software is something for you to consider. The earlier versions of the program created output files with the ".spo" extension, however, the current version of the software no longer uses these files for output and lacks the capability to read them. As a result, IBM provided a free viewer program that can open said files.
Navigate to the SPSS Legacy Viewer site.
Click one of the links to download the viewer (each one corresponds to a different language.)
Extract the contents of the file.
Double-click the "setup.exe" file to start the installation process. Once the process is complete, you'll be able to open and view ".spo" files.
