Answer 1

The following worked for me with a regular expression:

In Sublime:

1. Open the replace panel with CTRL + H
2. Make sure that regular expressions are enabled. It is the left icon ".*" in the same row as the search field (ALT + R).
3. Enter in "Find What": ^([^;]*);.*$
4. Enter in "Replace With": \1
5. Find and replace all

I tested it on Windows, on Mac you probably have to use the CMD instead of the CTRL key.
