VBA Code To Find And Replace Words Within Specific File Names In A Folder
What This VBA Code Does
I often have a routine of copying files from one month to another. The only problem with this sort of process is I have to go through and modify all the file names to reflect the current month or time period. As you can imagine, this can be quite a timely task....and timely tasks are perfect for automation with VBA!
Macro To Perform Find Replace on File Names
This macro will go through and perform a simple find and replace on all the files within a user-selected folder. The macro has three inputs that allow you to customize the find/replace terms, as well as the ability to target specific file types (ie .pdf or .ppt).
The below VBA macro code also uses a custom user-defined function which you will also need to paste into your code module. This function is written out later on in this article. Enjoy!
'PURPOSE: Modify Specific Text Within Files of a Folder
Dim FileList As Collection
Dim FileName As Variant
Dim ParentFolder As String
Dim FindTerm As String
Dim ReplaceTerm As String
Dim ExtensionFilter As String
Dim NewFileName As String
Dim ChangeCount As Integer
FindTerm = "January"
ReplaceTerm = "February"
ExtensionFilter = ".xls" 'Leave empty to change all file types
'Retrieve Target Folder Path From User
'Launch Folder Dialog Box
Set FldrPicker = Application.FileDialog(msoFileDialogFolderPicker)
'Record User's Selection
.Title = "Select A Target Folder"
.AllowMultiSelect = False
If .Show <> -1 Then Skip = True
If Not Skip Then ParentFolder = .SelectedItems(1)
'In Case User Cancels
If ParentFolder = "" Then Exit Sub
'Create a list of files within Specified Folder
Set FileList = PullFileNames(ParentFolder, "*" & ExtensionFilter & "*")
'Loop through list of files
For Each FileName In FileList
If FileName Like "*" & FindTerm & "*" Then
'Perform Find/Replace on file name
NewFileName = Replace(FileName, FindTerm, ReplaceTerm)
Name FileName As NewFileName
ChangeCount = ChangeCount + 1
MsgBox ChangeCount & " file(s) renamed within folder"
'Open Windows Explorer to see changes (optional)
Shell "C:\WINDOWS\explorer.exe """ & ParentFolder & "", vbNormalFocus
Function To Create List Of Files Within Parent Folder
The below code is also needed as a part of this process. The below VBA function creates a Collection (ie list) of all the files within a given parent folder. This list of file names is then passed back to our main VBA macro to change the names of the files.
Private Function PullFileNames(Path As String, Optional FileExt As String = "") As Collection
'PURPOSE: Create A List of Specific Files Within A Folder
Dim MyCollection As New Collection
Dim FileName As String
'Ensure folder path has a slash at the end
If Right(Path, 1) <> "\" Then Path = Path & "\"
'Get first file that meets extension criteria within folder
FileName = Dir(Path & FileExt)
'Loop through all files in folder
Do While Len(FileName) > 0
'Store Filename into a collection (list)
MyCollection.Add Path & FileName
'Next file meeting extension criteria (if any left)
FileName = Dir()
'Output files that meet criteria
Set PullFileNames = MyCollection
