vcard2to3

Convert vcards from version 2.1 to version 3.0.

I wrote these scripts to convert contacts exported from an Android 4.x phone and import them into Nextcloud. It worked for me, your mileage may vary.

The scripts are rather simple, they don't cover all differences between 2.1 and 3.0.

vcard2to3.py

vcard2to3.py is the conversion script. Quickstart:

git clone https://github.com/jowave/vcard2to3.git
cd vcard2to3
./vcard2to3.py your_file.vcf

The output will be a file your_file.vcf.converted.

To show available command-line arguments run:

./vcard2to3.py --help

usage: vcard2to3.py [-h] [--in_encoding IN_ENCODING]
                    [--out_encoding OUT_ENCODING] [-r REMOVE]
                    [--remove_card REMOVE_CARD] [--remove_dollar]
                    infile [outfile]

Convert VCard 2.1 to VCard 3.0.

positional arguments:
  infile                the input filename
  outfile               the output filename, defaults to the input filename
                        with ".converted" appended, this file will be
                        overwritten if it exists

options:
  -h, --help            show this help message and exit
  --in_encoding IN_ENCODING
                        the encoding of the input file (default: platform
                        dependent)
  --out_encoding OUT_ENCODING
                        the encoding for the output file (default: platform
                        dependent)
  -r REMOVE, --remove REMOVE
                        remove lines matching regex REMOVE, can be given
                        multiple times
  --remove_card REMOVE_CARD
                        remove vcards for which any line matches regex
                        REMOVE_CARD, can be given multiple times
  --remove_dollar       remove "$" in N and FN values

vcard_merge.py

Merge and sort vcards. With vcard_merge.py you can remove duplicate contacts. The contacts are sorted and merged by FN and duplicate lines within one contact are omitted. You may have to manually edit the result.
