Hello Tomas,
there is a free software developed by CDC called CDC EZ-Text which assists researchers create, manage, and analyze semi-structured qualitative databases. I would advice you to have a look at it. You can reach me through nutritionistbgt@gmail.com

Try EPI INFO freely downloadble from WHO and CDC. Initially it may appear not user friendly but once u get the hung of it, it's an excellent software gives out with 95% CI

Hello Tomas,

Unless I missed something in your question, you are asking about free software to perform qualitative data analysis, right?
I am not aware of any freeware for this purpose but you may want to download and use a Trial versions for i.e Nvivo (14 days) after filling a form.here. Of course, you need to take time to review and be familiar with its environment in the manual before you download. .here
Another option would be using excel for qualitative data analysis. an example of spreadsheet is here link. I hope this helps.
