In Excel 2013 you can use the DECIMAL function to convert "googlecom" (without .) to a number (e.g. if you use a numeric format up to 36, so 0-9 A-Z) and the BASE function to convert the outcome to hexadecimal, returning 2ACFBE9E2CB6, but I don't think this does make much sense at all.
At risk of stating the now obvious ;-) ColA - <23:14:18> 24000FD1 - The input string from the uart. ColC - =MID (A1,11,10) - pick out the variable length hex string. - the hex string isn't a fixed length & mid must attach nulls or spaces to it. ColD - =HEX2DEC (C1) And so the number conversion barfs.
Next. 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... [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.
Debug.Print. End Sub Public Function HexStringToByteArray(hexString As String) As Byte() Dim i As Long ReDim bytes(1 To Len(hexString) / 2) As Byte For i = 2 To Len(hexString) Step 2. bytes(i / 2) = "&H" & Mid(hexString, i - 1, 2) Next. HexStringToByteArray = bytes.
I know you can create a DEC2HEX formula. I wanted to convert Hex to Ascii. When I use HEX2DEC, it puts the ASCII number instead of the actual character. For instance, if I put the HEX number 4A in Cell A1, I want Cell A2 to display a capital J instead of the number 74 which is J in ASCII.
test = 10. Dim ans As String. ans = Evaluate("DEC2HEX(" & test & ")") MsgBox ans. End Sub. That said, you have been given a much better option here, as VBA has the Hex function already (something I did not know prior to this). ans = Hex (test) would be better to use in this case.
The decimal number from 0 to 127 is allocated to each one of those, including letters of the numbers, punctuation marks, and the English alphabet. To manually convert ASCII to decimal, identify the character in the ASCII table, and pick the decimal number against each character in your ASCII string. Regards Alxender
HEX2DEC (number) Number is the hexadecimal number you want to convert. Number cannot contain more than 10 characters (40 bits). The most significant bit of number is the sign bit. The remaining 39 bits are magnitude bits. Negative numbers are represented using two's-complement notation.
Re: Alphanumeric string conversion into hexadecimal then report the number of bytes. Well, you are going to struggle - from XL Help (Specifications and Limits): Total number of characters that a cell can contain :- 32,767 characters. Length of formula contents :- 8,192 characters. Internal length of formula :- 16,384 bytes.
