Macro to merge data from 100 worbooks in a folder

[lcon]

Hi,

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.

[VBA]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
ThisWorkbook.Activate
If Sheets("Summary").Len(Range("A1")) = 0 Then
Sheets("Summary").Range("A1").PasteSpecial (xlPasteAll)
Else:
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
ThisWorkbook.Activate
If Sheets("Analysis").Len(Range("A1")) = 0 Then
Sheets("Analysis").Range("A1").PasteSpecial (xlPasteAll)
Else:
Sheets("Analysis").Range("A1").End (xlDown)
ActiveCell.Offset(1, 0).PasteSpecial (xlPasteAll)
End If

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

End Sub[/VBA]

hi icon.

wellcome to VBAX.


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