I would like to import data for fields with multiple locales with the FeedMe plugin. I have to create the JSON feed, so how can I do that? Thanks for your help!
I found out, what my mistake was: If you import only one locale the fields must not be mandatory, otherwise you get an error about fields (the ones in the other locale) being empty.
Never used the plugin, but it seems like they cover this topic in their FAQ:
Can I import content into a specific Locale?
