I need to parse the output of Google Script logger.log - parsing

Question

I'm writing a small script to pull the user list out of an email group and add certain individuals to a different "master" group. My Log Output of the looks like what you see below. The sis only adding the first name. Does anyone know how to paste the whole list into a gmail group or is there a way to put the output of the Logger.log into a .csv and then loop through it to add each name individually?
Log Output:
[16-06-20 08:05:31:123 PDT] [name#domain.com, name#domain.com,
name#domain.com, name#domain.com, name#domain.com, name#domain.com,
name#domain.com, name#domain.com, name#domain.com, name#domain.com,
name#domain.com] [16-06-20 08:05:32:205 PDT]
Current code :
function getGroupMembers() {
var values = SpreadsheetApp.getActiveSheet();
var groupEmail = values.getRange(17, 5).getDisplayValue();
var userEmail = values.getRange(17, 4).getDisplayValue();
var group = GroupsApp.getGroupByEmail(userEmail);
var users = group.getUsers();
for (var u = 0; u < users.length; u++) {
var member = {
email : users,
role : 'MEMBER'
}
}
member = AdminDirectory.Members.insert(member, groupEmail);
Logger.log('User %s added as a member of group %s.', userEmail, groupEmail);
}

Can you tell me if this fits your needs. I put the insert in the for loop and set email using users[u] instead of users. Otherwise, the loop was useless.
By the way, the language used by Google Script is JavaScript.
function getGroupMembers() {
var values = SpreadsheetApp.getActiveSheet();
var groupEmail = values.getRange(17, 5).getDisplayValue();
var userEmail = values.getRange(17, 4).getDisplayValue();
var group = GroupsApp.getGroupByEmail(userEmail);
var users = group.getUsers();
for (var u = 0; u < users.length; u++) {
var member = {
email : users[u],
role : 'MEMBER'
};
Logger.log('u=' + u + '---' + users[u]);
//member = AdminDirectory.Members.insert(member, groupEmail);
}
Logger.log('User %s added as a member of group %s.', userEmail, groupEmail);
}
