We all differ in how we analyse the data. Some people use stats packages like SPSS, SAS, Q software, etc. Others use market research specific software such as Surveycraft, OzQuest, Plenari, Quantum, etc. or even Excel.
Sawtooth is very much about the data capture.
You need to decide what software you need for analysing the output and that depends on what you're trying to get out of the data?
Sawtooth provides a number of export options which can be found under the FILE tab under Data export.
