How to save data in the form of columns?
The official developers offer a tutorial with full information on how to work with the Data Toolbar. This process is also explained. In fact, there is an example on the Tutorial page where it's explained how to save the data in the forms through columns.
I advise reading all the information on the following page: http://datatoolbar.com/tutorial.html
If it's too long to read, use the video tutorial: http://datatoolbar.com/tutorial_video.html
