I found a macro that will import multiple text files into Excel.
However, the macro assumes that the data being imported uses the pipe
character (|) as a delimiter between fields. However, my data does not
have the pipe character. I've imported one of the text files manually
and gotten what the fixed widths need to be (all text files are
identical in layout). I've tried mycolwidths, but am doing something
wrong. Here's the original code with delimter in it.... Thanks!

Sub CombineTextFiles()
Dim FilesToOpen
Dim x As Integer
Dim wkbAll As Workbook
Dim wkbTemp As Workbook
Dim sDelimiter As String

On Error GoTo ErrHandler
Application.ScreenUpdating = False

sDelimiter = "|"

FilesToOpen = Application.GetOpenFilename _
(FileFilter:="Text Files (*.txt), *.txt", _
MultiSelect:=True, Title:="Text Files to Open")

If TypeName(FilesToOpen) = "Boolean" Then
MsgBox "No Files were selected"
GoTo ExitHandler
End If

x = 1
Set wkbTemp = Workbooks.Open(FileName:=FilesToOpen(x))
wkbTemp.Sheets(1).Copy
Set wkbAll = ActiveWorkbook
wkbTemp.Close (False)
wkbAll.Worksheets(x).Columns("A:A").TextToColumns _
Destination:=Range("A1"), DataType:=xlDelimited, _
TextQualifier:=xlDoubleQuote, _
ConsecutiveDelimiter:=False, _
Tab:=False, Semicolon:=False, _
Comma:=False, Space:=False, _
Other:=True, OtherChar:="|"
x = x + 1

While x <= UBound(FilesToOpen)
Set wkbTemp = Workbooks.Open(FileName:=FilesToOpen(x))
With wkbAll
wkbTemp.Sheets(1).Move After:=.Sheets(.Sheets.Count)
..Worksheets(x).Columns("A:A").TextToColumns _
Destination:=Range("A1"), DataType:=xlDelimited, _
TextQualifier:=xlDoubleQuote, _
ConsecutiveDelimiter:=False, _
Tab:=False, Semicolon:=False, _
Comma:=False, Space:=False, _
Other:=True, OtherChar:=sDelimiter
End With
x = x + 1
Wend

ExitHandler:
Application.ScreenUpdating = True
Set wkbAll = Nothing
Set wkbTemp = Nothing
Exit Sub

ErrHandler:
MsgBox Err.Description
Resume ExitHandler
End Sub
