Awesome!<p>By the way, you say no one claims to love Excel. I claim to love Excel! I loved it since the first time I saw it with the embedded Windows 2.0 runtime in the late 80s. When I saw that I immediately deleted all copies of 1-2-3 and Quattro and never looked back.<p>So, you made an old Excel user happy by adding Octopart, which I've already loved as well.
Is it open source ? An add-in in my business Excel sheet is something I would prefer not to have to <i>only</i> trust. Anyway, very nice and I would totally understand if you keep it closed.
