VBA code to open all excel files in a folder - vba

Question

I was working with a vba and I'm trying to open all excel files in a folder (about 8-10) based on cell values. I was wondering if this is the right approach to opening it, it keeps giving me syntax error where I wrote the directory. and when I rewrote that section, the vba only shot out the msgbox which meant it had to have looped and did something right? but didn't open any files. Any information will help. Thank you guys so much for taking the time to help me in any way.
Sub OpenFiles()
Dim search As Worksheet
Dim customer As Range
Dim customerfolder As Range
Dim QualityHUB As Workbook
'setting variable references
Set QualityHUB = ThisWorkbook
Set search = Worksheets("Search")
Set customer = Worksheets("Search").Range("$D$1")
Set customerfolder = Worksheets("Search").Range("$D$3")
With QualityHUB
If IsEmpty((customer)) And IsEmpty((customerfolder)) Then
MsgBox "Please Fill out Customer Information and search again"
Exit Sub
End If
End With
With QualityHUB
Dim MyFolder As String
Dim MyFile As String
Dim Directory As String
Directory = "O:\LAYOUT DATA\" & customer & "\" & customerfolder"
MyFile = Dir(Directory & "*.xlsx")
Do While MyFile <> ""
Workbooks.Open Filename:=MyFile
MyFile = Dir()
Loop
MsgBox "Files Open for " + customerfolder + " complete"
End With
End Sub

This worked for me perfectly
Sub OpenFiles()
Dim search As Worksheet
Dim customer As Range
Dim customerfolder As Range
Dim QualityHUB As Workbook
'setting variable references
Set QualityHUB = ThisWorkbook
Set search = Worksheets("Search")
Set customer = Worksheets("Search").Range("$D$1")
Set customerfolder = Worksheets("Search").Range("$D$3")
With QualityHUB
If IsEmpty((customer)) And IsEmpty((customerfolder)) Then
MsgBox "Please Fill out Customer Information and search again"
Exit Sub
End If
End With
With QualityHUB
Dim MyFolder As String
Dim MyFile As String
Dim Directory As String
Directory = "O:\LAYOUT DATA\" & customer & "\" & customerfolder & "\"
MyFile = Dir(Directory & "*.xlsx")
Do While MyFile <> ""
Workbooks.Open Filename:=Directory & MyFile
MyFile = Dir()
Loop
MsgBox "Files Open for " + customerfolder + " complete"
End With
End Sub
one of the issue was, you had to write
Workbooks.Open Filename:=Directory & MyFile
instead of
Workbooks.Open Filename:=MyFile

Corrected some issues with your code and cleaned it up, give this a try. I think the big issue was you had an extra double-quote, and you missing the ending \ in the Directory line:
Sub OpenFiles()
Dim QualityHUB As Workbook
Dim search As Worksheet
Dim customer As String
Dim customerfolder As String
Dim Directory As String
Dim MyFile As String
'setting variable references
Set QualityHUB = ThisWorkbook
Set search = QualityHUB.Worksheets("Search")
customer = search.Range("$D$1").Value
customerfolder = search.Range("$D$3").Value
If Len(Trim(customer)) = 0 Or Len(Trim(customerfolder)) = 0 Then
MsgBox "Please Fill out Customer Information and search again"
Exit Sub
End If
Directory = "O:\LAYOUT DATA\" & customer & "\" & customerfolder & "\" '<--- This requires the ending \
MyFile = Dir(Directory & "*.xlsx")
Do While Len(MyFile) > 0
Workbooks.Open Filename:=Directory & MyFile
MyFile = Dir()
Loop
MsgBox "Files Open for " + customerfolder + " complete"
End Sub

I found this code online and it will open all the excel files in a folder, you can adapt the code to apply a function to the workbook, once it is open.
Option Explicit
Type FoundFileInfo
sPath As String
sName As String
End Type
Sub find()
Dim iFilesNum As Integer
Dim iCount As Integer
Dim recMyFiles() As FoundFileInfo
Dim blFilesFound As Boolean
blFilesFound = FindFiles("G:\LOCATION OF FOLDER HERE\", _
recMyFiles, iFilesNum, "*.xlsx", True)
End Sub
Function FindFiles(ByVal sPath As String, _
ByRef recFoundFiles() As FoundFileInfo, _
ByRef iFilesFound As Integer, _
Optional ByVal sFileSpec As String = "*.*", _
Optional ByVal blIncludeSubFolders As Boolean = False) As Boolean
Dim iCount As Integer '* Multipurpose counter
Dim sFileName As String '* Found file name
Dim wbResults, file, WS_Count, i, gcell, col, finRow, wbCodeBook As Workbook, lCount, name, looper
Dim WorksheetExists
Set wbCodeBook = ThisWorkbook
'*

Dim oFileSystem As Object, _
oParentFolder As Object, _
oFolder As Object, _
oFile As Object
Set oFileSystem = CreateObject("Scripting.FileSystemObject")
On Error Resume Next
Set oParentFolder = oFileSystem.GetFolder(sPath)
If oParentFolder Is Nothing Then
FindFiles = False
On Error GoTo 0
Set oParentFolder = Nothing
Set oFileSystem = Nothing
Exit Function
End If
sPath = IIf(Right(sPath, 1) = "\", sPath, sPath & "\")
'*
'* Find files
sFileName = Dir(sPath & sFileSpec, vbNormal)
If sFileName <> "" Then
For Each oFile In oParentFolder.Files
If LCase(oFile.name) Like LCase(sFileSpec) Then
iCount = UBound(recFoundFiles)
iCount = iCount + 1
ReDim Preserve recFoundFiles(1 To iCount)
file = sPath & oFile.name
name = oFile.name
End If
On Error GoTo nextfile:
Set wbResults = Workbooks.Open(Filename:=file, UpdateLinks:=0)
''insert your code here
wbResults.Close SaveChanges:=False
nextfile:
Next oFile
Set oFile = Nothing '* Although it is nothing
End If
If blIncludeSubFolders Then
'*
'* Select next sub-forbers
For Each oFolder In oParentFolder.SubFolders
FindFiles oFolder.path, recFoundFiles, iFilesFound, sFileSpec, blIncludeSubFolders
Next
End If
FindFiles = UBound(recFoundFiles) > 0
iFilesFound = UBound(recFoundFiles)
On Error GoTo 0
'*

End Function
