use VBA to covert .xls to .xlsx

[north123]

I have around 150 excel files in old format ".xls", I want to convert these .xls files to .xlsx format with VBA. Anybody could you please help, is there a way to do this in VBA without opening the old files then saving them as .xlsx? Because in BVA using codes for opening and saving take quite a long time. It would be great if someone konws how to do this without actually opening the old files. Many thanks!

Hi,

Sub kTest()

Dim fName As String
Dim MyFolder As String

MyFolder = "C:\Test\" '<<== adjust to suit

If Right$(MyFolder, 1) <> "\" Then MyFolder = MyFolder & "\"

fName = Dir(MyFolder & "*.xls")

Do While Len(fName)
Name MyFolder & fName As MyFolder & Replace(fName, ".xls", ".xlsx", , , 1)
fName = Dir()
Loop

End Sub

What happens if they have macros?

Since the OP wants it to be converted as xlsx, I guess the xls files have no macros.

If he understands that nuance of 2007/2010. Worth asking.
