Qualtrics is a tool that you can use to design and conduct both simple and complex surveys. There are all kinds of possibilities in terms of structure and the type of questions. The results are clearly presented and easy to export into Excel or SPSS.
When your survey is finished and can be closed, save all collected data appropriately, for example in OneDrive. Qualtrics itself is not a good place to store your data.
With Microsoft Forms, you can quickly design a form, survey or quiz and share it with people. Forms itself creates handy charts and graphs of the results, but you can also download the data as Excel or .csv file for your own analysis. More info on Microsoft Forms
