Explanation of Concepts - Excelcification
Nice. I wrote my own version of this with a little more explanation a long time ago at
http://aboutdev.wordpress.com/2009/12/19/excelcification-brain-teaser-code/. Although it's not quite an optimized version!
FYI. The base 26 arithmetic is called hexavigesimal and Excel's maximum column is XFD which converts to 16383 (using 0 as the first cell) which is coincidentally exactly 2^14 cells.
Can anyone guess as to why it is 2^14??
