[Suggestion] deduping contacts


I have ~400 contacts, some of which are duplicates. Are there any built in /available methods for deduping my contacts?


I implemented a merge functionality when I maintained the app. Isn’t that available anymore?


One option is to use Thunderbird with the sogo connector

Export everything as a csv file, de-dupe in your favorite spreadsheet application. (Address Book -> Tools -> Export)

Delete and then Re-import. (Address Book -> Tools -> Import)


Cardbook for Thunderbird has such a feature. I use the contacts optimizer Android App which works flawlessly.


FWIW, I finally installed khard on my laptop, and I just merge dupes in khard and then sync with Nextcloud. It doesn’t do the batch process that I really want, but it’s good enough.
