Notepad++ Insert characters every 2 characters of a string [duplicate]

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++?

Answer 1

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.

Answer 2

How about:

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

You have then to remove the last , if requested.
