John has a column of invoice numbers in a worksheet. He has a directory on the network where staff save a PDF of the actual invoice and name it using the same invoice number that is in the worksheet. Each invoice number in the worksheet should have a correspondingly named PDF in the directory on the network. John is looking for a way, within Excel, to check and verify that a PDF really does exist for each invoice number.
There is no way to do this using built-in Excel commands. You can, however, create a macro that will do the checking for you. For instance, consider the following simple user-defined function:

Function FileExists1(sPath As String)
FileExists1 = Dir(sPath) <> ""
End Function
The routine simply returns a True or False value, based on whether the specified file exists. The value that is passed to the function needs to include a full path and file name. For example, if the file specification (including the path) were in cell A1, you could use the following in a cell:
=FileExists1(A1)
You may not, however, want to put the full path name into the cell. In that case, you could specify it in the actual formula, in this way:
=FileExists1("c:\your\path\here\" & A1 & ".pdf")
Of course, you could instead specify the path in the user-defined function:
Function FileExists2(sFile As String)
sPath = "c:\your\path\here\" & sFile & ".pdf"
FileExists2 = Dir(sPath) <> ""
End Function
With such a function you could easily create a formula in your worksheet that would "flag" any invoices missing from the directory:
=IF(FileExists2(A1),"","Missing Invoice")

Hello,
Thank you for your amazing tips!
I cannot seem to get this working. No matter what I try I seem to get FALSE as a return. What am I doing wrong? I have tried all the methods shown above. My corresponding file name is listed in column B and I want to use this to check if a pdf is listed in a folder.
Thank you.
