Importing Album Metadata from Text Files

I’m trying to create a file with album metadata in both English and the original language. I have already used the File > Export function to get the data out. However, I’m struggling with the import process.

I understand that I should use Convert > Text file - Tag, but do I really have to manually enter every single placeholder? Is there a more efficient way to import all the tags from the file at once without mapping each field by hand?

I wonder what you mean by

MP3tag cannot "guess" which section of the record corresponds to which field - if there is data that should be omitted or swapped.
So, yes, you have to tell MP3tag the sequence of the fields.
