Generating outputs (datafiles)

There are 4 main forms of output file from PsychoPy:

• Excel 2007 files (.xlsx) see Excel Data Files for more details
• text data files (.csv or .dlm) see Delimited Text Files for more details
• binary data files (.psydat) see PsychoPy Data Files for more details
• log files (.log) see Log Files for more details

Binary data files (.psydat)

It is strongly recommended that you produce this form of file from all of your experiments even if you do not intend to use it. These files contain all the information about the experiment that was run and can be used to (re)create Excel and delimited files and even the experiment code itself.
