Thanks for your reply. I don't know how to preserve initial format of the file here, so I'll replace empty cells of.csv with null.

Username; Asset Name

Corinna Mayer;JKDef4574

Janek Huska;NAdf8f48g5

Eric Shtits;JSd5345kPFl

null;A878rfgP56

null;KDLefrtgt

Erik Fisher;UiO8trve

As you can see Eric Shtits owns 3 asset names in according to this .csv file, so two fields that supposed to be keys are empty.And I need to implement a solution that will be able to detect that all three asset names belong to one person. Regards, Kazak
