Hello,

I have a list of clients, emails, domains. And for every domain the client
has there is a row in the spreadsheet:

Some One, me@example.com, someone1.com
Some One, me@example.com, someone2.com
Some One, me@example.com, someone3.com
Some Other, you@example.com, someother.com
Some Thing, they@example.com, something.com
Some Thing, they@example.com, something1.com

I would like to combine the domains for the same clients using some
delimiter (

Thank you.
