Notepad++ Regular Expression From InitCaps to UnderscoreRT

Question

I am using Notepad++. I was wondering if I could change all occurences like the following from

DONT CONVERT ALL CAPS. TextToConvert

to

DONT CONVERT ALL CAPS. Text_To_Convert

using regular expressions in find and replace fields.

Thank you in advance.

That’s awfully similar to [this answer](http://stackoverflow.com/questions/6322906/utf8-correct-regex-for-camelcase-wikiword-in-perl/6323679#6323679), amongst many others. — tchrist, Jun 13 '11 at 14:33

Try replacing ([a-z])([A-Z]) with \1_\2.

Just tried it on My Notepad++, and the \1_\2 worked perfectly. I didn't know notepad++ could do that. – JohnathanKong Jun 13 '11 at 14:41
It worked but not in all caps. I have edited the question. Thank you :) – Nick Binnet Jun 13 '11 at 14:49
It shouldn't have any problems with `ALL CAPS`, make sure that "match case" is checked in the search dialog. – Qtax Jun 13 '11 at 14:53
