Issue with saving a workbook
Created originally on Bitbucket by esp198 (Esper Achkar)
I ran into an the following error on a script I was working on after updating my openpyxl package to version 2.5.14: "Exception Occured: I/O operation on closed file". reverting back to the older version (2.5.12) solved this issue. PS: It was the exact same code I ran in both versions
