DELETE DUPLICATE DATA TOOL

I was searching for a duplicate remover tool on the web when I finally stumble on the site called Sobolsoft. It has a comprehensive list of excel, word, and open office add-ons. Not free though but it is really worth the price. I downloaded the trial version of Excel Unique & Duplicate Data Remover 7.0 that has only a size of 1.2 MB. How i wish it is totally free. It will really be a great help to hasten my tedious job of determining duplicate data on my excel report file.
