In this post we are going to see how to merge the multiple Excelsheets data in to one Excelsheet using VBA Macro, sometimes there is a scenario where you have same structured data in multiple Excelsheets, you may want that data to collate in to one excelsheet, To do this we are going to do a programming which will have two buttons , one is for the browse the folder where you can find the all Excelsheets which are need to merge under one folder path, next button is used to merge.


First we have to check whether Excel is a macro enabled , to do this we have enable macro using the following steps in mentioned in the below url.

Then now need to Developer Tab and click on the Activex Controls and Drag the Two buttons, Then right click on the both the buttons and edit the name of that, Then we have to double click on each button and start writing the code.















First we have to browse a folder where we are kept the files which are needs to merge., Let we start write the code for Browse.


Code for Browse:
*********************
Private Sub CommandButton1_Click()
    Browse
End Sub


Sub Browse()
  Dim folderdlg As FileDialog
  Set folderdlg = Application.FileDialog(msoFileDialogFolderPicker)
  folderdlg.AllowMultiSelect = True
  folderdlg.Show
  
  If folderdlg.SelectedItems.Count > 0 Then
    folderPath = folderdlg.SelectedItems(1)
  End If
  
End Sub






Click on the Merge button, and start typing the code for the Merge.

Code for Collate
**********************
Private Sub CommandButton2_Click()
    Merge
End Sub

Sub Merge()
    
    Dim ProBook As Workbook
    Dim mSheet As Worksheet
    Dim cFileName As String
    Dim savefilepath As String
    Dim cRow, cColumn  As Integer
    Dim pRow, pColumn As Interior
    Dim firsttime As Boolean
    
    Dim filedlg As FileDialog
    
    If folderPath = "" Then
        MsgBox "Please select the folder, for merge the files, then click Merge"
    End If
    
    If folderPath <> "" Then
   
    folderPath = folderPath & "\"
   
    Set filedlg = Application.FileDialog(msoFileDialogSaveAs)
    filedlg.Show
    firsttime = True
    If filedlg.SelectedItems.Count > 0 Then
    
        savefilepath = filedlg.SelectedItems(1)
        cFileName = Dir(folderPath & "*.xl*")
          
        Set mSheet = Workbooks.Add(XlWBATemplate.xlWBATWorksheet).Worksheets(1)
        cRow = 1
        cColumn = 1
            
        Do While cFileName <> ""
           
            Set ProBook = Workbooks.Open(folderPath & cFileName)
      
            Dim LastRow As Long
            Dim lastCol As Long
            Dim srcRange As Range
            Dim dstRange As Range
            
            lastCol = ProBook.Worksheets(1).Cells(1, Columns.Count)_
                      .End(xlToLeft).Column
                   
            LastRow = ProBook.Worksheets(1).Cells.Find(What:="*", _
                       After:=ProBook.Worksheets(1).Cells.Range("A1"), _
                       SearchDirection:=xlPrevious, _
                       LookIn:=xlFormulas, _
                       SearchOrder:=xlByRows).Row
            
          Dim col_letter As String
          
          col_letter = Column_Letter(lastCol)
          If firsttime Then
            Set srcRange = ProBook.Worksheets(1).Range("A1:" & col_letter & LastRow)
          Else
            Set srcRange = ProBook.Worksheets(1).Range("A2:" & col_letter & LastRow)
          End If
                        
          Set dstRange = mSheet.Range("A" & cRow)
          Set dstRange = dstRange.Resize(srcRange.Rows.Count, _
             srcRange.Columns.Count)
             
          ' Copy over the values from the source to the destination.
          dstRange.Value = srcRange.Value
          
          ' Increase row so that we know where to copy data next.
          cRow = cRow + dstRange.Rows.Count
          
          
          ' Close the source workbook without saving changes.
          ProBook.Close savechanges:=False
          
          firsttime = False
          
          ' Use Dir to get the next file name.
          cFileName = Dir()
          
        Loop
    
    End If
    
    mSheet.Columns.AutoFit
    mSheet.SaveAs (savefilepath)
    
    
    End If
    
    
    
End Sub

Function Column_Letter(lngCol As Long) As String
    Dim vArr
    vArr = Split(Cells(1, lngCol).Address(True, False), "$")
    Column_Letter = vArr(0)
End Function






Click on the browse button and select the folder, You can see this folder have three excel files, data1.xlsx, data2.xlsx, data3.xlsx




Click in the Merge button, Give the name of the excel file as "MergeData" in which you have to save the collated data, thats it, All data are merged in one excel, in this sample we are collating three Excel files









Data1.xlsx





Data2.xlsx







Data3.xlsx






Output:
