I am trying to format fake data from the Faker API. I am using pandas to store it into a data frame. I have figured out how to strip and replace any errors like no spacing, improper spacing, removing parenthesis, country code, and extensions. The main issue I am having is when numbers are coming out like this: xxxxxx-xxxx instead of like xxx-xxx-xxxx.
