Extract and convert vcf contacts from emails in python

27 May, 2021

I wasn’t able to export my contacts from my iphone (iOS 11). Thus I mailed each contact to myself using an alias e.g. john.doe+contact@example.com. I’m using mu (mail indexer/searcher) version 1.6.4 for my emails. Everything else happens below:

Extract vcf file from email

contacts=~/tmp/iPhoneContacts
rm -r $contacts
mkdir $contacts
cd $contacts

foundEmails=$(mu find to:$myemail --fields "l")

for email in $foundEmails
do
  mu extract $email '.*.vcf'
done

Export vcf to tsv file

import fnmatch
import os
import re
import phonenumbers

ROOTPATH = '/home/ra/tmp/iPhoneContacts/'
PATTERN = '*.vcf'
TSV = open('/home/ra/tmp/iPhoneContacts/iPhoneContacts.tsv', 'w')


def contacts():
    l = set()
    for root, dirs, files in os.walk(ROOTPATH):
        for filename in fnmatch.filter(files, PATTERN):
            l.add(os.path.join(root, filename))
    return (l)


contactsList = contacts()
print("Total %s files:" % (PATTERN), len(contactsList))
for contactFile in contactsList:
    with open(contactFile, "r") as f:
        #Gets Peter Mueller Meier.contact from /home/ra/tmp/iPhoneContacts/Peter Mueller Meier.contact
        contactName = contactFile[(contactFile.rfind('/')) + 1::]
        #Gets Peter Mueller Meier from Peter Mueller Meier.contact
        contactName = contactName.split(".")[0]
        #Gets remaining words after space e.g. Mueller Meier from Peter Mueller Meier
        contactName = contactName.split(" ")
        #Gets Peter from Peter Mueller Meier
        contactFirstName = contactName[0]
        #Gets Mueller Meier from Peter Mueller Meier
        contactLastName = " ".join(
            contactName[1:]) if (len(contactName)) > 1 else ""

        numbrs = [
            phonenumbers.format_number(match.number,
                                       phonenumbers.PhoneNumberFormat.E164)
            for match in phonenumbers.PhoneNumberMatcher(f.read(), "CH")
        ]

        print(contactFirstName,
              contactLastName,
              "\t".join(numbrs),
              sep="\t",
              file=TSV)
TSV.close()
