I agree with the responses. You show them, and briefly explain how they help you make sure the audit program runs as designed.
Let me add that logs aren't necessarily the same thing as audit reports and audit notes, in which your company's sensitive details would most likely be buried.
Logs instead are, in my experience, built to show what audits took place with whom and when, results and actions on results, reassessment and closure dates, and perhaps short notes the auditor uses to manage the audit process.
It's about structure, not content, and shows there is a method to make sure all the steps in the process take place. This can be done with spreadsheets as well as with simpler methods like paper, and more complex methods as proprietary software.
