VBA Code to Merge Multiple Excel Workbooks

VBA Code to Merge Multiple Excel Workbooks

October 30, 2017

There's some great VBA code posted to Experts Exchange by Professor JimJam which you can use merge multiple Excel workbooks.

 

Note the line in the code where you need to specify the range that you are collecting:

 

Sub MergeTest()

    Dim SummarySheet As Worksheet
    Dim FolderPath As String
    Dim SelectedFiles() As Variant
    Dim NRow As Long
    Dim FileName As String
    Dim NFile As Long
    Dim WorkBk As Workbook
    Dim SourceRange As Range
    Dim DestRange As Range
    Dim LastRow As Long

    ' Create a new workbook and set a variable to the first sheet.
    Set SummarySheet = Workbooks.Add(xlWBATWorksheet).Worksheets(1)

    ' Open the file dialog box and filter on Excel files, allowing multiple files
    ' to be selected.
    SelectedFiles = Application.GetOpenFilename(filefilter:="Excel Files (*.xl*), *.xl*", MultiSelect:=True)

    ' NRow keeps track of where to insert new rows in the destination workbook.
    NRow = 1

    ' Loop through the list of returned file names
    For NFile = LBound(SelectedFiles) To UBound(SelectedFiles)
        ' Set FileName to be the current workbook file name to open.
        FileName = SelectedFiles(NFile)

        ' Open the current workbook.
        Set WorkBk = Workbooks.Open(FileName)

        ' Get row number of last used row
        LastRow = WorkBk.Worksheets(1).Cells.Find(What:="*", _
                                                  After:=WorkBk.Worksheets(1).Cells.Range("A1"), _
                                                  SearchDirection:=xlPrevious, _
                                                  LookIn:=xlFormulas, _
                                                  SearchOrder:=xlByRows).Row

        ' Set the cell in column N to be the file name.
        SummarySheet.Range("N" & NRow).Value = FileName
        
        ' Create header row
        Set SourceRange = WorkBk.Worksheets(1).Range("A1:M1")
        Set DestRange = SummarySheet.Range("A1:M1")
        DestRange.Value = SourceRange.Value

        ' Set the source range to be B1 through M?.
        ' Modify this range for your workbooks. It can span multiple rows.
        Set SourceRange = WorkBk.Worksheets(1).Range("A2:M" & LastRow)

        ' Set the destination range to start at column A and be the same size as the source range.
        Set DestRange = SummarySheet.Range("A" & NRow)
        Set DestRange = DestRange.Resize(SourceRange.Rows.Count, SourceRange.Columns.Count)

        ' Copy over the values from the source to the destination.
        DestRange.Value = SourceRange.Value

        ' Increase NRow so that we know where to copy data next.
        NRow = NRow + DestRange.Rows.Count

        ' Close the source workbook without saving changes.
        WorkBk.Close savechanges:=False
    Next NFile

    ' Call AutoFit on the destination sheet so that all data is readable.
    SummarySheet.Columns.AutoFit
End Sub

 

 

 

Play the macro, and it will prompt you to select the workbooks you want to merge.    So from files like these:

 

 

. . . is generated a workbook like this, combining the content of all four:
