How to open CSPLAN files

Did your computer fail to open a CSPLAN file? We explain what CSPLAN files are and recommend software that we know can open or convert your files.

What is a CSPLAN file?

CSPLAN files are SPSS Sampling Plan files, which you can read more about below.

The CSPLAN file extension indicates to your device which app can open the file. However, different apps may use the same file extension for different types of data. So a CSPLAN opener may not be able to open all kinds of CSPLAN files. In this case, though, we only know of one specific use.
