A simple Python script can be made to parse the table, copy and paste the Wikipedia table into a text file called “test.txt” and run the following script.
import re
f = open("test.txt", "r")
y = ""
for x in f.readlines():
# Remove all anything that is not a digit, a comma, or space
x = x.replace("\n", "")
x = re.sub("[^\d|,| ]", "", x)
y += x + ","
f.close()
print "var areacodes = Array(" + y[0:len(y)-1] + ");"
