View Full Version : Macro to merge data from 100 worbooks in a folder

03-10-2012, 09:19 AM

I have around 100 workbooks in a folder. Each of these workbooks have 2 sheets, Summary and Analysis. I want a macro to merge the Analysis worksheet from these 100 workbooks into one workbook.The column structure in all the Analysis sheets are the same.I've tried a couple of macros but none of them seem to work according to my requirement.

Any help would be appreciated.

This should get you started.

Sub OpenallFilesCopyandPaste()
Dim strPath As String
Dim strFile As String
Dim strName As String

'store your file path
sPath = "C:\users\jonathan\desktop\"
sFil = Dir(sPath & "*.xls")

Do While sFil <> ""
strName = strPath & strFile
Workbooks.Open (strName)

'specify range to copy for summary tab
Sheets("Summary").Range(Range("A1"), Range("A1").End(xlDown)).Copy

'paste into summary tab of thisworkbook
If Sheets("Summary").Len(Range("A1")) = 0 Then
Sheets("Summary").Range("A1").PasteSpecial (xlPasteAll)
Sheets("Summary").Range("A1").End (xlDown)
ActiveCell.Offset(1, 0).PasteSpecial (xlPasteAll)
End If

'specify range to copy for analysis tab
Sheets("Analysis").Range(Range("A1"), Range("A1").End(xlDown)).Copy

'paste into analysis tab of thisworkbook
If Sheets("Analysis").Len(Range("A1")) = 0 Then
Sheets("Analysis").Range("A1").PasteSpecial (xlPasteAll)
Sheets("Analysis").Range("A1").End (xlDown)
ActiveCell.Offset(1, 0).PasteSpecial (xlPasteAll)
End If

Workbooks(sFil).Close (False)
strFile = Dir

End Sub

hi icon.

wellcome to VBAX.

MyPath = "C:\Users\xxx\yyy"
with your files' location...
(add headers to the final sheet manually)

Sub Basic_Example_1()

Dim MyPath As String, FilesInPath As String

'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
