I'm stuck on a couple macros and would really appreciate any help. I need two different ones:

1. Delete all columns that HAVE NOT BEEN edited at all (text modification, added, etc.)

2. Delete a specified range of rows that have been edited at all (text modification, added, etc.)

Thank you all in advance! I'm having a terrible time trying to figure out how to get excel to understand that a change has been made to the document.
