Here are two example cvs files. The hard part is match data could be in any column.

It looks quite messy. How are you supposed to identify the names and company names that you want to compare?

In this example I would be hoping to match "Dr. Toy Story" in csv1 to "Dr. Toy Story" in csv2. This example doesn't contain an institute match. In need to compare each string between each set of comas to each string, again in between commas as it's csv in the second file. At match I'd like to return the line containing the match for each and write it to a new file.
