From here:

First download and install the TextFX plugin, instructions given below.

Download the plugin from SourceForge: http://downloads.sourceforge.net/project/npp-plugins/TextFX/TextFX%20v0.26/TextFX.v0.26.unicode.bin.zip

Open the zip file and extract NppTextFX.dll

Place NppTextFX.dll in the Notepad++ plugins directory, such as: C:\Program Files\Notepad++\plugins

Start Notepad++, and TextFX will be one of the file menu items

Check the following options

a) +Sort ascending

b) +Sort outputs only UNIQUE (at column) lines

enter image description here

Then select a block of text (ctrl+A to select the entire document). Then click "Sort lines case sensitive" or "Sort lines case insensitive"
