From the Web page, on your projects you can export the log of all fields of a form. 
To do so you need to follow the next steps : 

     1a. From the form directly, you can click on the top right corner of your screen and choose <Export logs> 

     1b. Or from the forms module page, you can also scroll right and click on the first form export logo to <Export logs> 

     2. A CSV is being downloaded, open it; on each line, you will have all the info about what and who filled it up.
