My steps to extract the data:
1. Utility - Strings, Action ""Remove Non-word Charachters"" --> Output: last name, first name, email@mail.com; last name2, first name2, mail2@mail.com; last name3, first name3, email3@mail.com
2. Utility - Strings, Action ""Split Text"" with Semikolon --> Output: Column1
row1 last name, first name, email@mail.com
row2 last name2, first name2, mail2@mail.com
row3 last name3, first name3, email3@mail.com
An now I'm not sure what I have to do.
