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] [-p]
infile [outfile]
Convert VCard 2.1 to VCard 3.0.
positional arguments:
infile
outfile
optional arguments:
-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,
can be given multiple times
--remove_dollar remove "$" in N and FN values
-p, --prune_empty remove vcards which have only FN but no additional
fields
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.
