How can I export the language file for sending to my translators?

How can I export the language file to send to my translators so that it can be uploaded back to jotform when translated?

Unfortunately, we don't have a feature that would allow you to export/import the translations. You have to do the translation again on the other form. But I think this is a good feature so I'm forwarding this thread to our developers. We can't promise you any timeframe for this, but if there are updates, you should know it through this thread.
