MAC address format convert with excel. From MS Excel, 1. Put a raw MAC address: ex) 55 on A1. TCP Throughput Calculation Formula. Free GeoIP Lookup Database – Find Website IP. Many websites and software provide free GeoIP lookup services. If we input an IP address to these services, they provide us Excel IP address lookup facility with below listed information to help us understand the actual address of the User of that IP.
Oh, I wouldn't bet on that! Try the code below (assuming macros are acceptable). Open your workbook, select the sheet that you'll enter MAC addresses into. Right-click on the name tab and choose View Code from the list. Copy the code below and paste into the module presented to you.
Change those first 2 Const values pointing to column B and row 2 to match the reality of your worksheet. Close the VBA Editor (Alt+Q or the red-x). Try it out by entering some MAC addresses into the column. If you like it and want to keep it, save the workbook as a macro-enabled workbook, type.xlsm or.xlsb.
I don't think you can do this with a custom number format. Put the following function in a module: Function FormatMAC(varMAC) As String Dim i As Long For i = 1 To Len(varMAC) 2 FormatMAC = Mid(varMAC, Len(varMAC) + 1 - 2.
i, 2) & ':' & FormatMAC Next i If FormatMAC ' Then FormatMAC = Left(FormatMAC, Len(FormatMAC) - 1) End If End Function With MAC addresses in A1:A100, you can enter =FormatMAC(A1) in cell B1 and fill down. If you'd rather update the values themselves, select the range with MAC addresses and run the following macro (which uses the FormatMAC function): Sub FormatMACSelection Dim rng As Range Application.ScreenUpdating = False For Each rng In Selection rng.Value = FormatMAC(rng.Value) Next rng Application.ScreenUpdating = True End Sub Regards, Hans Vogelaar.

Ok figured out how to add a module. Alt - F11 opens the VBA side.
But in Excel 2007 there is NOTHING in any of the menus there that indicates this, i had to find out from reading articles. So i copied/pasted the function, and saved it, but in the spreadsheet if i try to enter a function =FormatMAC(a1) then hit enter, it, the cell, says 'Name?' As if it cannot find it at all. When powering on the computer today and opening up that file, it had a warning message that a macro is there from a source that cannot be verified, enable macros anyway? So it looks like Excel at least found it, but in the worksheet it will not let me use it. Ok, got it to work, i added it again as a module as this time it saw it.
So the module as written, when trying to use formatmac(a1) it says syntax error, but formatmac produces 11:22:33:44:55 ok. Now it totally works.
Instead of me typing in the cell, a1, i clicked on the cell and it highlighted and did whats expected. After doing just 1 cell, moving the mouse around to the lower right corner it turned into a plus sign, i clicked on the finished cell and dragged or drug downward and it filled in the rest of them just fine.
(i was probably trying too hard to make that happen before). I tried this with the upper function and it also worked; works with alpha and numeric thanks again Hans! Brad R Windows and Mobile platform Developer California USA.
