If that is THE reason for the product to exist, you are marketing this all wrong. You list features and say what it can do, but you are really selling robustness, stability and clarity. Don't sell the product, sell the problem. Spaghetti code in Excel. Untouchable formulas created by some ex-employee. Replacing a magic variable in 30,000 cells, etc. At the end, show how your product solves it. You need some sample before and afters. This is what the formula looked like before, here's how it was abstracted and this is what that change enables. Ideally your product would be a service that a company pays for where you come in a help clean up their files. If possible, I would see if you could find a company willing to let to try and use them as a case study. That would be 1000% more effective than worrying about marketing details.
