 So if you have a dict or a text file in the mentioned format you could use it as dictionary for UltraSpellChecher, by default UltraSpellCheher doesn’t detect any Microsoft Word dictionaries, but if they are in appropriate format you could use them with UltraSpellChecker .

Please let me know if you have any further questions.
