# converting HEX string to ascii string

##### New Member
I saw your example converting hex to ascii "=CHAR(HEX2DEC("4A"))".
I would like to know how to convert a string of hex to ascii. There is example: 5238304d33335446462 and convert to R80M33TFF

Your example has an odd number of characters in it (total length equals 19 characters)... your conversion seems to ignore the lone 2 at the end. Assuming you will always pass an even number of hex digits, here is a UDF (user defined function) that you can use...
Code:
``````[table="width: 500"]
[tr]
[td]Function HEX2ASCII(S As String) As String
Dim X As Long
For X = 1 To Len(S) Step 2
HEX2ASCII = HEX2ASCII & Chr("&H" & Mid(S, X, 2))
Next
End Function[/td]
[/tr]
[/table]``````
If you want to be able to pass an odd number of characters and have the odd last character ignored (like your example does), then use this UDF instead...
Code:
``````[table="width: 500"]
[tr]
[td]Function HEX2ASCII(ByVal S As String) As String
Dim X As Long
If Len(S) Mod 2 Then S = Left(S, Len(S) - 1)
For X = 1 To Len(S) Step 2
HEX2ASCII = HEX2ASCII & Chr("&H" & Mid(S, X, 2))
Next
End Function[/td]
[/tr]
[/table]``````
HOW TO INSTALL UDFs
------------------------------------
If you are new to UDFs, they are easy to install and use. To install it, simply press ALT+F11 to go into the VB editor and, once there, click Insert/Module on its menu bar, then copy/paste the above code into the code window that just opened up. That's it.... you are done. You can now use HEX2ASCII just like it was a built-in Excel function. For example,

=HEX2ASCII(A1)

If you are using XL2007 or above, make sure you save your file as an "Excel Macro-Enabled Workbook (*.xlsm) and answer the "do you want to enable macros" question as "yes" or "OK" (depending on the button label for your version of Excel) the next time you open your workbook.
