Rallybound allows administrators to edit registrants in bulk, by uploading a CSV file to the admin panel. To do so, follow the instructions below:
Log in to your admin panel (at yourcampaign.com/admin)
Click "People" and then "Registrants" in the left sidebar
Click "Bulk Edit" at the top of the window
Click "Download CSV Sample Template" in the pop up window
After the Sample Template downloads, open it in your spreadsheet program, and add existing registrants (with their information to change) to the spreadsheet*. Important: When editing/adding to the template, enter the MemberIDs of only the registrants you want to edit in the first row. Enter any column data you want to edit.
Once you've finished entering your data into the spreadsheet, save it as a CSV file
Back in the admin panel > "Bulk Edit" pop up window, click "Browse", and attach the CSV file you just saved. Then click "Upload".
