Do I need to have every cell in a CSV file filled in order for the import to work?

 The Serial Number value and Loaner fields are required, but each other cell can be blank. When imported, blank fields are read by Fleet as null. Null fields will preserve the field as is if a value for that field has already been set in Fleet, or leave the field empty if one has not.

 

Note: if you include Organizational Unit (OU) assignments in your CSV file, each entry in the OU column must be preceded by a forward slash ( / ), and must also correspond to an OU name that is already in your organization.
