JavaScript Hexdump coder/decoder
You need JavaScript 1.2 (IE4.0 or Netscape4.0 and above) enabled because this is no cgi-bin.
I am not sure if this works with Netscape, too. I do not use Netscape.

Type here the hexdump and see plaintext above:
Type here your plaintext and see hexdump below:
Notes on the hex text field:
This translates into and from unicodes. The Euro sign € thus is translated to 20AC.

If the system does not see any spaces in a line, only ISO LATIN characters (00 to FF) are assumed.

Short last lines inherit the "space setting" from the line before. Everything behind a ! to the end of the line is ignored. A hex "00" is internally interpreted as "01", because JavaScript cannot handle "\0" in strings.
