Thanks! This is a huge savings in time for us

@maxwellmckinnon Did you ever find a method to import the source controlled VBA files back into the excel workbook?

ran into an issue

FileSystemObject needs Microsoft Scripting Runtime

also allow the macro access the vba-code, as described above

Instead of using fso, I prefer to use mkdir:

 If Dir(directory, vbDirectory) = "" Then
      MkDir directory
    End If

Any idea how to use git shell and at the end of your code directly push it to git?

@danielleevandenbosch

you can instead add the line:
Set fso = CreateObject("Scripting.FileSystemObject")

after your error on line 15.

@steve-jansen

Upon Changing Application.StatusBar = False it has worked Perfectly!

In case you are interested, there is an alternative approach which does not require any VBA at all. The trick is to use a pre-commit hook to execute some Python code that extracts the VBA code from the workbook file (without using Excel itself): https://www.xltrail.com/blog/auto-export-vba-commit-hook

Awesome. Thank you for this!

I just changed line 41 to prepend the active workbook name:

path = directory & "" & ActiveWorkbook.Name & " " & VBComponent.Name & extension

I commented-out the last two lines and added a Msgbox that uses the text from one of the lines. The Msgbox displays immediately upon completion instead of a delay at the status line.

The end of the macro now looks like this:
' Application.StatusBar ...
' Application.OnTime ...
MsgBox "Successfully exported " & CStr(count) & " VBA files to " & directory
End Sub

Clearer in hindsight, but it took me some time to get there: To save the macros in the Personal Workbook, the Personal Workbook needs to be visible when the macro is started.

Making the Personal Workbook visible was not intuitive for me and, in Excel 2013, it requires accessing the Unhide button on the View tab of the ribbon. Then the macros are saved to the 'VisualBasic' folder at:
C:\Users*username*\AppData\Roaming\Microsoft\Excel\XLSTART\VisualBasic,
as advertised in the msgbox when the macro is done.

This is FANTASTIC! Thank you!!!!

Great Tool! Thank you a lot!

why is it adding blank lines in my userform .frm files ?

github is telling me the code changed but it really didnt.

This is great. it worked on my machine except I have all my macros as an Add-in .xlam, multiple modules. Any way to get revise this code to export those? I bet it's just one change on line 25

Edit: I figured it out. It was trivial btw. Just change ActiveWorkbook to ThisWorkbok on line 25.
Thanks to https://sourcedaddy.com/ms-excel/distribute-macros.html for the clue.

If anyone is looking for the equivalent code to import VBA, you might use this

Sub ImportVisualBasicCode()
 
    Dim oFSO As Object
    Dim oFolder As Object
    Dim oFile As Object
    Dim i As Integer
    Dim directory As String
     
    Set oFSO = CreateObject("Scripting.FileSystemObject")
     
    Set oFolder = oFSO.GetFolder(ActiveWorkbook.path & "\VisualBasic")
     
    For Each oFile In oFolder.Files
     
        directory = ActiveWorkbook.path & "\VisualBasic\" & oFile.Name
        ActiveWorkbook.VBProject.VBComponents.Import directory
        
        If Err.Number <> 0 Then
            Call MsgBox("Failed to import " & oFile.Name, vbCritical)
        End If
     
    Next oFile
 
End Sub

Occasionally when i am importing and exporting modules. The name will come in with a suffix of 1. Does any one know of a fix? This is annoying as eventually the name will look like this "modulename1111111111"

This might happen because you're importing a module with the same name as an already existing module. You should delete it before importing.

Thank you for this!

This routine saved me a ton of time converting a Excel 2007 set of VBA code to Excel 2019 VB.NET. This routine helped me get past the first step in the process (using Visual Studio).

Great code, thanks!

@ArthurAttout yes I do delete all the modules before importing but sometimes it still happens. But rarely.

This is super helpful. For anyone who is working with macros in word documents, not excel, simply replace all instances of ActiveWorkbook with ActiveDocument

One other note. Every time you run this the FRX files will show up as having changed in GIT. This is a known issue and some cursory reading suggests fixing this wouldn't be simple. hilkoc/vbaDeveloper#5

This is amazing. Thank you.
I changed the directory definition to meet my needs and had to remove the line to "ClearStatusBar". Instead of using the status bar at all, I created a MsgBox line to notify that the data was exported and where.

I then saved this as an add-in so that it's available for any file I open now.

It works great and I'm able to keep this in version control with GitHub now.

directory = "C:\Users\<REDACTED>\OneDrive\VisualBasic\" & ActiveWorkbook.Name

MsgBox ("Successfully exported " & CStr(count) & " VBA files to " & directory)
'REMOVED: Application.StatusBar = "Successfully exported " & CStr(count) & " VBA files to " & directory
'REMOVED: Application.OnTime Now + TimeSerial(0, 0, 10), "ClearStatusBar"

Thank you so much for posting this! Super time saver.

Also, Thanks Joe Gearhart for:

MsgBox ("Successfully exported " & CStr(count) & " VBA files to " & directory)

Wonderful!
