I use the following code to try and open a downloaded csv file:
========================

Function OpenCSVFile(csvFileName) As Boolean
On Error GoTo FailedOpen

Application.Workbooks.Open csvFileName
OpenCSVFile = True
Exit Function

FailedOpen:
OpenCSVFile = False

End Function
==================

Sometimes the CSV is not guaranteed to be readable, and when it can't open,
a dialogue comes up saying "This file is not in a recognizable format." I
would hope this would be caught by "On Error", but it doesn't catch it. It's
a large batch process and I don't want it to be halted by a bad CSV file, i
want the error to be logged and continue.

Any idea on how I can prevent this? A way to supress the dialogue, or to
check a file for validity before even trying to open it?

Thanks,
Mayhew

I don't know much, but you might want to try

application.displayalerts=false/true 'false at the beginning, true at the end

at the beginning/end of the sub? I don't know much about formulas, so I
don't know if this would work with it.

Thanks for the suggestion. I neglected to mention that if you click past the
dialog , the corrupt file opens anyway, and I don't want my script running on
the garbage file. So I need some way of knowing in my code that the error has
occurred, and skipping over that file.
