3rd party Excel application validation?

Hello,

I have developed an Excel application and I am ready to put it up for sale on another company's website. But before they will allow that they want a 3rd party to validate the application for usability and to make sure that there are no bugs, malware, etc. associated with the file. Are there certified, reliable, and trustworthy companies out there that do this type of thing?

Many thanks in advance,

Unfortunately I cannot answer your question, but I applaud the purchasing company's thoroughness. If only Microsoft had the same tenacity in vetting its code-writers.

Best of luck with your endeavor!
