If you already have a collection of words in a plain ASCII (UTF-8) format, you can import them into Granule. The word pairs in your text file must be separated by one of the separator characters in the Import from CSV dialog. The text also must be in UTF-8 format. One way to check it out is to open your input file with gedit. If it doens't complain and you see all the text in it the way you've expected, then forge ahead.
To import, open a Deck file and click on Deck->Import from CSV menu entry.
The File Select dialog appears. Find and Select your input text file. The CSV Text Import dialog apears.
UNIX (LF) for UNIX files; Windows (CR+LF) for Windows files
Select word separator in the input file. If you have phrases, you might want to use Semicolon for a separator.
If selected, will ignore adjacent separators. For example, you might have a word list separated not by one but by loose number of white spaces. Selecting this option will let you treat multiple adjacent spaces as one separated between words.
