Please Note: This article is written for users of the following Microsoft Excel versions: 97, 2000, 2002, and 2003. If you are using a later version (Excel 2007 or later), this tip may not work for you. For a version of this tip written specifically for later versions of Excel, click here: Pulling Filenames into a Worksheet.
Carol has a directory with about 1,000 files with names such as YR1905-LIC12345-Smith,Harry-Brown,Mary. She would like to bring all of these filenames (not the files themselves) into a worksheet and separate the names at the dash. Thus, the example filename would actually occupy four cells in a single row. Carol figures this will take a macro to accomplish, but she's not sure how to access the filenames in that macro.
You can, of course, use a macro to do this, but you don't need to use a macro. You can, instead, use an old DOS-era trick to get what you need. At the command prompt (accessible through Windows: Start | All Programs | Accessories | Command Prompt), navigate until you are in the directory that contains the files. Then enter the following:
dir /b /a-d > filelist.txt
This creates a text file (filelist.txt) that contains a list of all the files within the current directory. Now, within Excel, you can follow these steps:
Figure 1. The Text Import Wizard.
The above steps are fairly easy to accomplish, particularly if you only need to get the file listing into Excel once in a while. If you need to do it more routinely, then you should probably seek a way to do it using a macro. The following macro will work very quickly:
Sub GetFileNames() Dim sPath As String Dim sFile As String Dim iRow As Integer Dim iCol As Integer Dim splitFile As Variant 'specify directory to use - must end in "\" sPath = "C:\" iRow = 0 sFile = Dir(sPath) Do While sFile <> "" iRow = iRow + 1 splitFile = Split(sFile, "-") For iCol = 0 To UBound(splitFile) Sheet1.Cells(iRow, iCol + 1) = splitFile(iCol) Next iCol sFile = Dir ' Get next filename Loop End Sub
When you run the macro, make sure that there is nothing in the current worksheet. (Anything there will be overwritten.) Also, you should change the directory path that is assigned to the sPath variable near the beginning of the macro.
If you get an error when you run the macro, chances are good that you are using Excel 97. The Split function (used to break the filename apart at the dashes) was not added to VBA until Excel 2000. If you are using Excel 97, then you can use the following routine to emulate what the Split function does:
Function Split(Raw As String, Delim As String) As Variant Dim vAry() As String Dim sTemp As String Dim J As Integer Dim Indx As Integer Indx = 0 sTemp = Raw J = InStr(sTemp, Delim) While J > 0 Indx = Indx + 1 ReDim Preserve vAry(1 To Indx) vAry(Indx) = Trim(Left(sTemp, J)) sTemp = Trim(Mid(sTemp, J, Len(sTemp))) J = InStr(sTemp, Delim) Wend Indx = Indx + 1 ReDim Preserve vAry(1 To Indx) vAry(Indx) = Trim(sTemp) Split = vAry() End Function
