This article assumes you have a list of email addresses in an Excel file column and you need to comma separate them to for email and project visibility filtering.
You can use the Excel formula 'CONCATENATE' to quickly add commas between the Email address for the following purposes:
1. Sending Email Newsletters
2. Adding Participant email address for Project Filtering (Visibility)
Please Note: Once you have used the formula 'CONCATENATE', copy the fields and use 'Paste Special' function to paste the values in the next field. This will remove the Excel formulae from the values
