Are you closer? 
Im trying do something similar, but im still on the beginnig because im looking for basic VLOOKUP function. Could you please write (or show) how to create data based on one value?
For example i have table with data:
And i want to show login user (in ListViewer as textitems) only data as are in the same row as login user (i know how to use LocalStorage and userid). But i dont know how to extract JSON from object based on e-mail.
I think that is interest even for rest of community 
thanks a lot for helping
