You can read text files or excel files. It's just a matter of whether you are reading one by or orlooping through everything in a folder. Google is your friend on this one. There are many examples. I believe you will need to reference Microsoft Scripting Runtime in your project. Below is just a single text file example, but you could write a loop to cycle through all text files in a folder.
Dim strFilename As String: strFilename = "C:\temp\yourfile.txt"
Dim strFileContent As String
Dim iFile As Integer: iFile = FreeFile
Open strFilename For Input As #iFile
strFileContent = Input(LOF(iFile), iFile)
'do SW work here.
Thanks for the reply. I also found this script as well, though I need the points to be connected so I can loft the sketches together.
