You can use the Autofill and Import options to fill in blank cells in the target language automatically, based on translations in other cells.

Autofill All and Autofill Current look for occurrences of identical (duplicate) text in the source language column of the open file.

Autofill by Name looks for occurrences of identical item names in the open file.

Import by Source Language and Import by Name compare the open file to another (external) .mdd file.
