I have had a look through the plugins as well as searched the forum for Notepad++ and have not seen a solution to editing data as hex in Notepad++.

I am after the same kind of functionality that UltraEdit offers (see the screenshot below) where you can edit the document either directly or via entering new hex characters.

    @Michael I don't think anyone thinks this is a bad question. People may just think it would fit better on another site, like Super User or Software Recommendations. Commented May 5, 2017 at 14:10

    Sometimes I wish all the sites just folded into StackOverflow as it is sometimes really hard to pick one that fits best. And if you do then that site generally gets less attention than SO itself. Commented May 6, 2017 at 6:08

There is an old plugin called HEX Editor here.

According to this question on Super User it does not work on newer versions of Notepad++ and might have some stability issues, but it still could be useful depending on your needs.

Roger that. It does not work in Notepad++ v6.5. If anyone has an answer to this question for recent versions of Notepad++, that would be great.
@FreekdeBruijn I think you mean "to Notepad++\plugins" Works for me too.
@Aleksandr Dubinsky Yes, you're right, thanks! So it's: moving HexEditor.dll back from Notepad++\plugins\disabled to Notepad++\plugins works for me in Notepad++ v6.5 UNICODE (Build time: 28 Sep 2013 - 22:29:19). I'm using Windows 7 64-bit.
nablex's answer is a good workaround as well
Seems to work in 6.8.8 as well.

Is a completely different (but still free) application an option? I use HxD, and it serves me better than the Notepad++ plugin. It can calculate hashes, open memory of a process, it is fast at opening files of any size, and it works exceptionally well with the clipboard.

I used to use the Notepad++ plugin, but not anymore.

According to some comments on Super User it still works :) It just should be copied back to the plugins folder (if it's in the disabled folder) or downloaded from Plugins Central. I have downloaded it a few minutes ago and succeeded in using it.

Of course, be warned: this plugin COULD be unstable in some situations - that's why it was disabled.

None of the Hex editor plugins from Plugins Central currently load correctly or work :(

The hex editor plugin mentioned by ellak still works, but it seems that you need the TextFX Characters plugin as well.

I initially installed only the hex plugin and Notepad++ would no longer pop up; instead it started eating memory (killed it at 1.2 GB). I removed it again and for other reasons installed the TextFX plugin (based on Find multiple lines in Notepad++)

Out of curiosity I installed the hex plugin again and now it works.

Note that this is on a fresh install of Windows 7 64 bit.

FWIW I also had success with this recipe.
