Once you have entered query constraints into the Archive query interface at http://almascience.org/aq and hit "Search" you will see the results of your query. In order to download the results table and look at it e.g. in Topcat (http://www.star.bris.ac.uk/~mbt/topcat/) or Excel, click with the mouse on "Export Table" and select the appropriate format (e.g. VOTable for Topcat and csv for Excel).
Such queries can also be launched programmatically by using our VO services. Examples are provided here: https://almascience.org/alma-data/archive/archive-notebooks
