Just export the template file from settings/languages, fill it and try to import. Get lots of errors:
There was an issue parsing your data. Details:
Row: 4 Too many fields: expected 1 fields but parsed 3,
Row: 5 Too many fields: expected 1 fields but parsed 2,
Row: 7 Too many fields: expected 1 fields but parsed 3,
Row: 8 Too many fields: expected 1 fields but parsed 3…
To check the problem, just download and save the template file and try to import it without any edits. The result is the same. Did anybody fix this problem?
