Thanks for taking the time to answer my question. The code you provided does do exactly what I wanted. Awesome! However, I receive a strange error messages upon attempting to open the CSV, after batch execution, in Excel.
The first dialog box I get is:
When I click "Yes", I receive a second dialog box:
If I then click "OK" to open in a different format, the file opens and displays fine, like a normal CSV.
Here is the modified file for reference: http://www.mediafire.com/file/ahg9j...
Since adding the column is one of the first steps in my intended workflow for these files, I want to ensure that I will not have any problems bringing these files into MS Access or other DB solution. I'm not sure why the file is attempting to be recognized as an SYLK file and no longer as a normal CSV after batch execution. Any ideas? Thanks again for your help.
