Convert email addresses to VCF format

[jehoshua]

We need to transfer some names and email addresses from Claws mail address book to a Samsung Galaxy Tab A. To understand what the Galaxy wanted , did an export of what is in the contacts app. It is in VCF version 2.1 an example from https://docs.fileformat.com/email/vcf/ as follows:

Output:
BEGIN:VCARD
VERSION:2.1
N:Gump;Forrest;;Mr.
FN:Forrest Gump
ORG:Bubba Gump Shrimp Co.
TITLE:Shrimp Man

Claws can export the address book contents to either HTML or LDIF format. Rather than get bogged down in converting from one of those formats to VCF, I have used the script at https://r3mlab.github.io/python/2018/07/...riter.html . After correcting a few errors, the current code is

#!/usr/bin/env python

import csv

def vcfWriter(name, email, phone, category):
    vcfLines = []
    vcfLines.append('BEGIN:VCARD')
    vcfLines.append('VERSION:4.0')
    vcfLines.append('FN:%s' % name)
    vcfLines.append('EMAIL:%s' % email)
    vcfLines.append('TEL:%s' % phone)
    vcfLines.append('CATEGORIES:%s' % category)
    vcfLines.append('END:VCARD')
    vcfString = '\n'.join(vcfLines) + '\n'
    return vcfString

# Get data from the CSV file
csvFile = open('contacts.csv')
csvReader = csv.reader(csvFile)
csvData = list(csvReader)

# Create the ouput file
outputFile = open('contacts.vcf', 'w')

# Iterate over the lines of the CSV table
for row in range(len(csvData)):
    if row == 0:
        continue # Skip the first row (headers)
    else:
        # Get contact data from current row
        name = csvData[row][0]
        email = csvData[row][1]
        phone = csvData[row][2]
        category = csvData[row][3]

        # Write the corresponding vCard string to the output file:
        outputFile.write(vcfWriter(name, email,phone, category))

# Don't forget to close both files
outputFile.close()      
csvFile.close()

The input data did have TAB as a delimeter, but that needed to be change to a delimeter of a COMMA to get it to work. Here is the input data, file file contacts.csv

Output:
Alice ,         [email protected], 0123456789, Friends
Bob, [email protected], 0987654321, Work

and the output data in file contacts.vcf is

Output:
BEGIN:VCARD
VERSION:4.0
FN:Bob
EMAIL: [email protected]
TEL: 0987654321
CATEGORIES: Work
END:VCARD

Note it is only reading the second line in the file, and not both. The version is easy to modify. As the exports from Claws mail are only HTML or LDIF format, they are quite different to a CSV file where it is only one row per person and all the fields are delimitered by a specific character.

So, I definitely need to move from using CSV to some sort of flat file format. The HTML looks quite messy and possibly hard to work with as there are cells within a table, lots of HTML code,etc. The LDIF on the other hand is like this

Output:
dn: uid=538705298
objectClass: person
objectClass: inetOrgPerson
cn: Forrest Gump
sn: Gump
givenName: Forrest
displayName: Forrest Gump
mail: [email protected]

The "dn: uid=" indicates a new dataset, the unique number there is irrelevant for this purpose. So in summary, how do I ensure all records are read in the above script, and how can the CSV be replaced with some sort of flat file processing please ?

Is the second part of the modifications suitable addressed by https://pypi.org/project/ldif/ ?
