When you export runbook from development environment and import in production generally this runbook imports also global settings and global configurations even if they are not referenced by the exported runbook. This is where this tool comes in help. The tool removes these global settings and configurations from the exported runbooks.
Author of the tool is Ryan Andorfer you can find more information about the tool on his blog.
SanitizeExport.exe can be download at codeplex.
