If these flat files are always the same layout, you may want to record a macro
when you do it by hand the next time.
Start a new workbook.
Tools|macro|Record new macro
Do all your importing and reformatting.
Include all the things you like (worksheet headers, print headers/footers/freeze
panes/Data|Filter|Autofilter)
Stop recording and save that workbook with the recorded code in it.
Put a giant button from the forms toolbar on the first worksheet in that
"importer" workbook. Assign your macro to the button.
You'll probably have to adjust the code a little to make it more generic. When
you recorded your macro, you got something that looked like:
Option Explicit
Sub Macro1()
Workbooks.OpenText Filename:="C:\myfile.txt", Origin:=437, StartRow:=1, _
DataType:=xlFixedWidth, FieldInfo:=Array(Array(0, 1), Array(15, 1), _
Array(41, 1))
End Sub
Well, instead of having your filename in the code, you can give the user a
chance to pick it themselves (take a look at getopenfilename in VBA's help):
Sub macro1A()
Dim myFileName As Variant
myFileName = Application.GetOpenFilename(filefilter:="Text Files, *.Txt", _
Title:="Pick a File")
If myFileName = False Then
MsgBox "Ok, try later" 'user hit cancel
Exit Sub
End If
Workbooks.OpenText Filename:=myFileName '....rest of recorded code here!
End Sub
And you may need to adjust some ranges (depending on what you did when you
recorded the macro). Post back with a snippet of your code (not the workbook)
and explain your problem.
But now whenever you need to import a text file with that layout, you can just
open your "importer" workbook and click the giant button.
