Here's the problem at hand: I have a file with some data like this:
Name;email;zip;status
Joe Doakes;joe@doakes.com;07123;A
Nancy Smith;nancy25@smith.com;98146;I
Armando Gonzales;armando@gonzales.com;77194;A
I want to semi-anonymize it by changing all the email addresses to end in @example.com
and replacing the ZIP code with a random 5-digit number.
