Hi all,

Say I have a few pdfs, I list location/file name in cell, 1 pdf file with 5 pages, and a few other pdfs, is there any vba code that can combine this into one pdf? Is this possible?
 

Excel Facts

Remove leading & trailing spaces
Save as CSV to remove all leading and trailing spaces. It is faster than using TRIM().
Hi john, i've tried it, do you have any documentation on setting this up? this is what I have so far:

Code:
Sub Combine()    
       
       Dim n As Long, PDFfileName As String
        
        n = 1
        Do
            n = n + 1
            PDFfileName = Dir(ThisWorkbook.Path & "firstpdf" & n & ".pdf")
            If PDFfileName <> "" Then
                'Open the source document that will be added to the destination
                objCAcroPDDocSource.Open ThisWorkbook.Path & "pathwithpdfs" & PDFfileName
                If objCAcroPDDocDestination.InsertPages(objCAcroPDDocDestination.GetNumPages - 1, objCAcroPDDocSource, 0, objCAcroPDDocSource.GetNumPages, 0) Then
                    MsgBox "Merged " & PDFfileName
                Else
                    MsgBox "Error merging " & PDFfileName
                End If
                objCAcroPDDocSource.Close
            End If
        Loop While PDFfileName <> ""
    
    
       End Sub

Is Acrobat Pro installed on your computer? If so, try this code, which merges the PDFs in column A of the active sheet starting at A2. In the VBA editor you must set a reference to Adobe Acrobat n.0 Type Library, via Tools -> References.

Code:
'References
'Adobe Acrobat 10.0 Type Library

Option Explicit

Public Sub Merge_PDFs()

    Dim objCAcroPDDocDestination As Acrobat.CAcroPDDoc
    Dim objCAcroPDDocSource As Acrobat.CAcroPDDoc
    Dim PDFfiles As Range, PDFfile As Range
    Dim n As Long
    
    With ActiveSheet
        Set PDFfiles = .Range("A2", .Cells(.Rows.Count, "A").End(xlUp))
    End With
    
    'Create Acrobat API objects
    
    Set objCAcroPDDocDestination = CreateObject("AcroExch.PDDoc")
    Set objCAcroPDDocSource = CreateObject("AcroExch.PDDoc")
    
    'Open first PDF file and merge other PDF files into it
    
    n = 0
    For Each PDFfile In PDFfiles
        n = n + 1
        If n = 1 Then
            objCAcroPDDocDestination.Open PDFfile.Value
        Else
            objCAcroPDDocSource.Open PDFfile.Value
            If Not objCAcroPDDocDestination.InsertPages(objCAcroPDDocDestination.GetNumPages - 1, objCAcroPDDocSource, 0, objCAcroPDDocSource.GetNumPages, 0) Then
                MsgBox "Error merging " & PDFfile.Value
            End If
            objCAcroPDDocSource.Close
        End If
    Next
    
    'Save merged PDF files as a new file
    
    objCAcroPDDocDestination.Save 1, ThisWorkbook.Path & "\Merged PDFs.pdf"
    objCAcroPDDocDestination.Close
    
    Set objCAcroPDDocSource = Nothing
    Set objCAcroPDDocDestination = Nothing

    MsgBox "Created " & ThisWorkbook.Path & "\Merged PDFs.pdf"
    
End Sub

Thanks for this, awesome macro.

I have a problem, sometimes at the beginning of the range, A2, it may be empty and the macro doesn't work. It works correctly if A2 has any patch, how can I fix this?

Replace the Set PDFfiles line with:
VBA Code:
        Set PDFfiles = .Columns("A").Find(What:="*", After:=.Range("A1"), LookIn:=xlValues)
        Set PDFfiles = .Range(PDFfiles, .Cells(.Rows.Count, "A").End(xlUp))

Thanks so much John, it works perfectly, cool!
