I confess I cannot quite work out a solution from what you've shared so far. Can export and share your OpenRefine project? Or recreate a smaller subset with some shareable representative data and share that as an OR project? The OR project contains a history of your steps as well as the data transformation at each step. Sharing a project may be the easiest way to explain the steps you've taken, and for others to understand the state of the problem.
How to: Save an OpenRefine Project:
Click the Export button in the top right ; select Export project.
Find the tar.gz file in your default OpenRefine Download directory.
Share it via Google Drive, Drobbox, box, etc.
