Notepad++ Insert characters every 2 characters of a string

Question

I have a string representing hex numbers, like this:

778206213082061D06092A

I want to get a string like this:

0x77, 0x82, 0x06, 0x21, 0x30, 0x82, 0x06, 0x1D, 0x06, 0x09, 0x2A

So every 2 characters, I want to insert , 0x Is this doable with Notepad++?

Yes, use macros - see https://www.cathrinewilhelmsen.net/2013/10/27/notepad-macros-a-basic-example/ for example. — Roman Hocke, Jan 25 '17 at 13:31
Any 2 characters or any alphanumeric or any ALLCAPS + digit? It would be best to show what you tried. — Wiktor Stribiżew, Jan 25 '17 at 13:32
Thanks. But I just found a very simple solution: Find: `(..)` and replace with `\1, 0x` — tzippy, Jan 25 '17 at 13:33
This will add `,` and a space before the first value on the line. — Wiktor Stribiżew, Jan 25 '17 at 13:35

Try this:

Find:

(..)

Replace:

0x\1,

The find expression (..) matches any two characters (dot matches anything), and the parenthesis allow us to capture those two characters. We can then replace with the hex expression, accessing those two captured characters by using \1 (or $1; Notepad++ will accept either). Note that there is a space after the comma in the replacement.

How about:

Ctrl+H
Find what: (..)
Replace with: 0x$1,
Replace all

You have then to remove the last , if requested.

This can be done without having to remove the final `,`. Just do not add it. Use a conditional replacement pattern. – Wiktor Stribiżew Jan 25 '17 at 13:36
@WiktorStribiżew:Certainly, but I can't find a simple way to not add it :( – Toto Jan 25 '17 at 13:41

Ctrl+H for Find & Replace
Tick Regular Expression
Find: ([A-Z0-9]{2}) & replace with 0x\1, (space on the end)
Find: , $ & replace with nothing. (to remove trailing ,)
