[notepad++] How can I convert uppercase letters to lowercase in Notepad++

I use Notepad ++ for coding mostly.

How can I convert capital letters to lowercase and vice versa?

This question is related to notepad++ case-sensitive

The answer is


You could also, higlight the text you want to change, then navigate to - 'Edit' > 'Convert Case to' choose UPPERCASE or lowercase (as required).


First select the text
To convert lowercase to uppercase, press Ctrl+Shift+U
To convert uppercase to lowercase, press Ctrl+U


Ctrl+A , Ctrl+Shift+U

should do the trick!

Edit: Ctrl+U is the shortcut to be used to convert capital letters to lowercase (reverse scenario)


In my notepad++ I press

Ctrl+A = To select all words

Ctrl+U = To convert lowercase

Ctrl+Shift+U = To convert uppercase

Hope to help you!


I had to transfer texts from an Excel file to an xliff file. We had some texts that were originally in uppercase but those translators didn't use uppercase so I used notepad++ as intermediate to do the conversion.

Since I had the mouse in one hand (to mark in Excel and activate the different windows) I disliked the predefined shortcut (Ctrl+Shift+U) as "U" is too far away for my left hand. I first switched it to Ctrl+Shift+X which worked.

Then I realized, that you can create macros easily, so I recorded one doing:

  • mark all
  • paste from clipboard
  • convert to upppercase
  • copy to clipboard

That macro got assigned that very shortcut (Ctrl+Shift+X) and made my life easy :)
