How to migrate Google Contacts?

[schildbach]

Google Contacts supports Export formats "Google CSV", "CSV for Outlook only" and "vCard for Android or iOS". None of that can be imported/uploaded into Radicale – I get an "Error: 400". Is there a way to migrate an entire Address Book?

Have you tried to move them with a client, e.g. Thunderbird with CardBook Add-on?

Well, I tried "Gnome Contacts" which doesn't seem to provide a way to add CardDAV-based contacts, even though I've set it up (and enabled it) in the Gnome Online Accounts.

On the mobile side I'm using DAVx5, which doesn't have a UI for the actual data at all. I hope I can continue using the "Google Contacts" app, similar to I was able to use the "Google Calendar" app for my CalDAV-based calendar via DAVx5.

So what I need is a way to import one of the above formats into the CardDAV-ecosystem. It would be unfortunate if one had to install Thunderbird plus an add-on from the app store just for that, and then uninstall it afterwards. Plus, you didn't say if it actually works – does it?

FN is mandatory, afair somebody provided a script to fix broken contacts, search in issues and dicussions.

also once solution is found, please contribute to a new a wiki page...potential useful also for others.

It would help a lot if Radicale would log the particular card it can't parse. Something like the text between (and including) the BEGIN and END lines.

Also, I think if Google produces invalid cards it might be worthwhile to implement a workaround for this specific problem.

I'll look for the repair script you mentioned.

Here is the "script" (from #1066 (comment)):

awk 'BEGIN{c=0} /FN:/{a=a+1} /END:VCARD/{b=b+1;if(b>(a+c)){c=c+1;print NR}} END{print a,b}' < contacts.vcf

It outputs line numbers of the END of cards without FN. (I had to ignore the last output line with two numbers – they didn't point to an invalid card.)

Note that in all such cases, I had entered just a company name (e.g. a restaurant), no person. And I added them quite recently.

I fixed it by duplicating the ORG line into FN. This seems like a easy workaround to support non-conformant Google Contacts exports.

Makes sense, added for events in the past but not for contacts, will be impemented by #1928
