Manage Pool Columns

From Pool home, click the Columns button in the top right to control which columns are visible and included in an export. If you're looking to manage column mapping, head to data > attributes.

Keep in mind there are required columns that you can't hide like email, name, tags, last emailed, and date added.

 If you see a fingerprint next to a column, that means it's a type of participant attribute called "identifier," which is used to uniquely identify participants to add or update data associated with them.

You can also rename and delete certain types of columns, as long as they are from uploads or automatic API imports. Metadata columns and screener question columns can't be edited here.

Exported CSV with custom columns

Keep in mind any custom columns you turn on will be included in an export, in addition to the required column.
