As an admin, you may want to populate or update your custom fields in Lattice all at once (instead of individually) for your employees. Before you can update your custom fields in Lattice, you first need to create them in Lattice. Learn how to create a custom field here.
After your custom field(s) and options have been created, follow these steps:
Step 1: Under Admin > People, click "Export CSV"
Step 2: Your new custom fields will be new columns at the end of your CSV. Fill in the proper information for each column.
Make sure that you are only filling in the columns with options that were set up with your custom field.
Step 3: Click Upload CSV and follow the instructions in the pop-up modal to load the new information back into Lattice.
