Also, as a side note since I like python, it's definitely not the only way to do python in Excel. With pyWin32, you can register python code as a COM server and call it from Excel in VB. Additionally there's projects like pyxll which, while not the prettiest, are at least free for non-personal use.
I will say this though - thank you, DataNitro, for having a free tier.
Edit: Reasons for downvotes, please? I have said nothing nonconstructive. I am seriously baffled as to why techies are still using Excel rather than an actual database.
Also, ain't no one smack talks mah spreadsheets. Thems run the business (in the insanely non-ideal real world, for better or worse).
(Irrelevantly, I'm reminded of http://www.youtube.com/watch?v=ziH9St7ajuw#t=39s)
To be sure, people do use Excel as a DB, but I think it's handier to think of it as an interactive mesh than a DB. Sort of like how pandas with IPython is a great way to interact with and explore data.
... Dang, imagine if you had pandas running with Excel on top. That would probably be pretty cool.
