One of the more helpful features associated with private galleries and its subject data is the ability to export your gallery and its data in a variety of formats. These options can be found in two places - under "Exports" in your job's sub navigation...
...and in your main Subjects Data section by accessing the "View/Edit" option.
There are three different types of exports:
Subject Data - This will export your subject data as a standard CSV file that can be imported into any spreadsheet software.
Yearbook - This will export your subject data (.txt file), along with the resized primary photo associated with each subject into a formatted PSPA archive.
Service Item - This will export your subject data (.csv file), along with with a primary photo associated with each subject. You can select from a list of crop templates or customize the crop.
