I want to send artist & track tag of a track to external translator like Qtranslate how can I do it?
You can export tag data to a text file with an export (see the help: https://docs.mp3tag.de/export)
You can import tag data from a text file with
Convert>Text file - tag
or an action of the type "Import text file"
Why would one want to translate
isn't that a name that stays as it is?
I want to see artist and title name for foreign languages like Japanese, Russian by sending to a translator quickly (if possible)
This is best done via User-defined Tools
