Rate my Product : QueryCell
sr3d: This is awesome!  Love the idea and the implementation looks really slick too.  I had to work on a huge excel file before (like 400,000 rows) and I so wished to have an add-on to run a simple SELECT query.Congrats on the bold move.  I am in the same boat -- just quit my job last Friday and will be working on my startup.  I wish you the best of luck!Alex
