I've installed the application and tested its functionality. From what I've seen, it appears that eTimeTrackLite will export the details of the employees to the CSV format. CSV format is fully supported by the Excel application, meaning that you can open it, save it and then import it back to the eTimeTrackLite application through the Import function accessible through the Utilities > Import employee details.
