Convert string to binary and hex. Dim s As String = 'Welcome+World People+TN G4444+44555+WWWW ' Dim byts As Byte = System.Text.ASCIIEncoding.ASCII.GetBytes(s) For Each b As Byte In byts Dim bnry As String = Convert.ToString(b, 2).PadLeft(8, '0'c) Dim hx As String = Convert.ToString(b, 16).PadLeft(2, '0'c) Debug.WriteLine(bnry & ' ' & hx) Dim fromHex As Byte = Convert.ToByte(hx, 16) 'convert. 1) Read the hex file: Look at File.ReadAllText ^ , or File.ReadAllLines ^ depending on how your hex files are organised. 2) Loop thorugh the file, converting the hex to bytes, using Convert.ToByte ^ (string, 16) for each hex character pair - again, without knowing your hex format, it is difficult to be specific. The uuencoding is a binary to ASCII encoding that comes from Unix where it was used for transmitting of binary files on the top of text-based protocols. Code page Encoder converts text data from one encoding to another one. Note that source code page for text inputs is always UTF-8. If you want to use another source code page, please use file. Here's a modified version of an earlier post (asc2bin and bin2asc) to convert an incoming ascii string to hex and out again. For example, this is really useful if you want to insert data into a mySQL database which contains both escaped and non-escaped characters. World's simplest online binary to hex converter. Just paste your binary numbers in the form below and they will instantly get converted to hex. Free, quick and very powerful. Paste binary, get hexadecimal.

Question or problem about Python programming:
How can I perform a conversion of a binary string to the corresponding hex value in Python?
I have 0000 0100 1000 1101 and I want to get 048D I’m using Python 2.6.
How to solve the problem:
Solution 1:
int given base 2 and then hex:
The doc of int:
int(x[, base]) -> integer
Convert a string or number to an integer, if possible. A floating
point
argument will be truncated towards zero (this does not include a string
representation of a floating point number!) When converting a string,
use
the optional base. It is an error to supply a base when converting a
non-string. If base is zero, the proper base is guessed based on the
string content. If the argument is outside the integer range a
long object will be returned instead.
The doc of hex:
hex(number) -> string
Return the hexadecimal representation of an integer or long
integer.
Solution 2:
Solution 3:
Use python’s binascii module
Solution 4:
Converting Binary into hex without ignoring leading zeros:
You could use the format() built-in function like this:
Solution 5:
Using no messy concatenations and padding :
Will give a hex representation with padding preserved
Solution 6:
This overview can be useful for someone: bin, dec, hex in python to convert between bin, dec, hex in python.
I would do:
Result: ‘048d’
Solution 7:
On python3 using the hexlify function:
Will give you back:
and you can get the string of it like:
gives:
Solution 8:
Solution 9:
For whatever reason I have had issues with some of these answers, I’ve went and written a couple helper functions for myself, so if you have problems like I did, give these a try.
They seem to work well.

Solution 10:
To convert binary string to hexadecimal string, we don’t need any external libraries. Use formatted string literals (known as f-strings). This feature was added in python 3.6 (PEP 498)
If you want hexadecimal strings in small-case, use small “x” as follows

Where bs inside f-string is a variable which contains binary strings assigned prior
f-strings are lost more useful and effective. They are not being used at their full potential.
