Confirm which links in a database are active and which are not active any longer.

I have a database in a WordPress website that includes links to other websites. I have been building this database for a long time, and we currently have 710 entries, and each entry has one link. I am contracting someone to go through the database and test every link. In addition, this person will create a list of the database entries in Excel and note which ones have active links and which ones have links that aren't working. I need to have this work done by 11/30/22.
