I developed a set of utilities for Excel (http://www.breezetree.com/spreadspeed/ http://www.breezetree.com/spreadspeed/), and I started adding some auditing features to it. After spending a few weeks on the auditing tools, I decided that I should do a little market research before investing more time on auditing features. Well, I'm glad I did because I found out that the market is saturated with spreadsheet auditing tools. Most are simple and inexpensive (like mine), but there are some fairly sophisticated tools out there. So my takeaway from this is not that there aren't sufficient auditing tools, but that the market needs a non-programmer, user-friendly way to build robust yet malleable models.
