Figured this out. I'm sure other people are going to read this as I did today.
You'll need two modules (one to extract hyperlinks and one to test file path directory)
Module1 (for hyperlinks)
Function HLink(rng As Range) As String
'extract URL from hyperlink
'posted by C.F. Stotch! - shoutout to Richard K!
If rng(1).Hyperlinks.Count Then HLink = rng.Hyperlinks(1).Address
Module2 (for directory test)
Function FileOrDirExists(PathName As String) As Boolean 'used to test filepaths of commmand button links to see if they work - change their color if not working
'Macro Purpose: Function returns TRUE if the specified file
Dim iTemp As Integer
'Ignore errors to allow for error evaluation
On Error Resume Next
iTemp = GetAttr(PathName)
'Check if error exists and set response appropriately
Select Case Err.Number
Case Is = 0
FileOrDirExists = True
FileOrDirExists = False
'Resume error checking
On Error GoTo 0
''''' AND BELOW IS WHAT YOU WOULD INSERT INTO YOUR SHEET AND ACTIVATE IT HOW YOU WISH, via command button or how you wish. I have it auto run when worksheet is activated :)
Private Sub TestFilesExist()
Dim xCheck As Integer
'starting in the 3rd row....
xCheck = 3
On Error GoTo 0
'Debug.Print Range("A" & xCheck).Value
While xCheck < 36
'xPather - checks if Z1 is a good path and then either highlights the actual cell in A column red if bad, or no fill if good.
Dim sPath As String
Dim XPather As String
'need a cell to put the hyperlink addresses into during the loop check as was not able to find the hyperlink address straight out of the cell containing the hyperlink. Extraction if you will. :)
ThisWorkbook.Sheets(1).Range("Z1").Value = "=HLink(A" & xCheck & ")"
XPather = ThisWorkbook.Sheets(1).Range("Z1").Value
'Tests if directory or file exists
If FileOrDirExists(XPather) = False Then
Range("A" & xCheck).Interior.ColorIndex = 3
Range("A" & xCheck).Interior.ColorIndex = xlNone
xCheck = xCheck + 1
