I have hundreds of very large Excel file with thousands of phone numbers in them.
I also have a long list of phone numbers to delete from each Excel file.
I need you to develop a way to be able to quickly delete those numbers from my Excel files.
(A sample of my Excel file will be sent to whoever is awarded the project)
***I am NOT asking for you to do the deletions, I am asking you to come up with a way for ME to do these deletions quickly
