Before you download your Data Cart, confirm the Data Cart contains all variables you want to include in your publication submission.
To browse additional datasets, select the Continue to Add More Items button.
To download the listed variables, select the Download Data Cart button. A JSON file (ppsc_variable_list.json) will be downloaded to your
computer's Download folder.
The JSON file format is what the data coordinating core will use to process a data set for you.
When preparing your publication submission, you will need to attach your downloaded JSON (ppsc_variable_list.json) file.
