Combine and Append data from multiple Excel workbooks into one worksheet

Question

Below I found a VBA Script online that takes all worksheets from workbooks in a directory, and combines them all in one workbook as separate sheets. However, I don't want them to be separate sheets. I want all data in the sheets to be in a single worksheet.

Sub GetSheets()
    Path = "Desktop\RandoDir"
    Filename = Dir(Path & "\*.csv*")
    Do While Filename <> ""
        Workbooks.Open Filename:=Path & Filename, ReadOnly:=True
        For Each Sheet In ActiveWorkbook.Sheets
            'MsgBox Filename      ---Debugging
            Sheet.Copy After:=ThisWorkbook.Sheets(1)
        Next Sheet
        Workbooks(Filename).Close
        Filename = Dir()
   Loop
End Sub

If I had data structured like this in two files:

   **File1**                **File2**
Header1|Header2    |     Header1|Header2
Tim    |Smith      |     Mike   |Jones

I want the merged worksheet to display

   **File3**
Header1|Header2
Tim    |Smith
Mike   |Jones

Answer 1

If VBA is not required, you could use DOS commands in the folder containing the CSVs

mergeCSVs.bat (in the CSV folder):

copy *.csv all.csv

echo Header1,Header2 > result.csv

type all.csv | findstr /v Header1,Header2 >> result.csv

del all.csv

---

• copy *.csv all.csv - combines all CSVs into a new file all.csv (with repeating headers)
• echo Header1,Header2 > result.csv - creates a new result.csv and writes the first row
• type all.csv | findstr /v Header1,Header2 >> result.csv
  • type all.csv - extracts all data from all.csv
  • findstr /v Header1,Header2 - filters out all header rows from all.csv
  • >> result.csv - appends all this data into the result.csv
• del all.csv - deletes temporary file all.csv

---

The results.csv will contain the merged data

csv1.csv:

Header1,Header2
Tim,Smith

csv2.csv:

Header1,Header2
Mike,Jones

result.csv:

Header1,Header2 
Tim,Smith
Mike,Jones

---

Notes:

• both csv files contain an empty line at the end
• they are comma-separated (not pipe-separated as in your example)

Answer 2

This will do what you want.

Sub Basic_Example_1()
    Dim MyPath As String, FilesInPath As String
    Dim MyFiles() As String
    Dim SourceRcount As Long, Fnum As Long
    Dim mybook As Workbook, BaseWks As Worksheet
    Dim sourceRange As Range, destrange As Range
    Dim rnum As Long, CalcMode As Long

    'Fill in the path\folder where the files are
    MyPath = "C:\Users\Ron\test"

    'Add a slash at the end if the user forget it
    If Right(MyPath, 1) <> "\" Then
        MyPath = MyPath & "\"
    End If

    'If there are no Excel files in the folder exit the sub
    FilesInPath = Dir(MyPath & "*.xl*")
    If FilesInPath = "" Then
        MsgBox "No files found"
        Exit Sub
    End If

    'Fill the array(myFiles)with the list of Excel files in the folder
    Fnum = 0
    Do While FilesInPath <> ""
        Fnum = Fnum + 1
        ReDim Preserve MyFiles(1 To Fnum)
