Based on the available sources, there is no person named ניצחת (Nitzachat) explicitly mentioned in the book of יהושע (Joshua) in the Tanakh or traditional commentary1. The most prominent figure in the book is יהושע בן נון (Joshua son of Nun), the leader who brought the Israelites into Canaan1.

If your query is asking whether someone named ניצחת appears in the narrative of Joshua—such as among the warriors, tribesmen, or notable figures—there is no evidence or mention in standard sources to support this12.

If you meant "who was victorious" (from the Hebrew verb ניצח, "to win" or "to be victorious"), the text primarily credits יהושע and the Israelites as achieving victory under God's guidance in multiple battles and conquests1.

If you are referring to another tradition, interpretation, or spelling, please clarify for further investigation. The possibility that ניצחת is a variant or transliteration of another name in the text does not match any known Hebrew or Aramaic rendering of famous figures from the book of Joshua in the sources provided1.
