This may sound counterintuitive, but all you need on an approved supplier list is a list of approved suppliers.
All the above suggestions are worthy, and I have seen all, less and more on lists of suppliers.
How you determined they are approved, what documentation you require, how often you poke your suppliers for updates on their required documentation, etc., can be in your supplier approval policy.
Do you really need a spreadsheet with all that info? Maybe, if your policy or standard require it or you have the free time to do nothing more than maintain a huge database or spreadsheet.
Why would you want to go to that effort though? If you have a policy that states what requirements there are for approved suppliers, certainly you would have that information on hand, right?
Why not have a simple list of approved suppliers, and if challenged by an auditor, produce the necessary documentation?
You can have a 400 column spreadsheet that lists a whole bunch of data, but as an auditor, I'd look at that and say "OK, show me the COA's you say you have, show me the Kosher Certs you have, and show me the most recent spec you have for that ingredient.
Point being, I understand the attraction of the "all inclusive Approved Supplier List", but it's one of those QA things that get out of control and tend to be more complicated than it needs to be.
