Saved Words and Phrases export ( in Excel Format )

i want to export the saved words and phrases ( in Excel format ) which are new and not which i have already done . is there a way ? i know that this feature exists if one wants to export into Anki format , but i dont use Anki and want to study in Excell sheets as i find it easier. but if i once export my phrases and words and if make new ones and want to export them again in Excel format , i also will again export the very same words and phrases which i have previously done and i dont want that . is there a way to go about it ?
