Notepad++ is a powerful text editor that many developers and writers use for its extensive features, including the ability to remove duplicate lines from a document. However, a common issue arises when users want to maintain empty lines in their text after removing duplicates. In this article, we’ll explore how to achieve this, providing easy-to-follow steps, and tips along the way.
Understanding the Problem
When you use Notepad++ to remove duplicate lines, you may notice that it also deletes empty lines. This can be problematic if you rely on these empty lines for formatting or separation between different sections of your text.
Original Code for Removing Duplicates
Typically, you might use the following process to remove duplicates in Notepad++:
- Select All Text: Press
Ctrl + A. - Remove Duplicates: Go to Edit > Line Operations > Remove Duplicate Lines.
This method, however, will strip away empty lines, which is not always desirable.
Keeping Empty Lines After Removing Duplicates
Solution
To preserve empty lines while removing duplicates in Notepad++, you can use a plugin or manually modify the text. Here’s a step-by-step guide for both methods:
Method 1: Using a Plugin
-
Install the "TextFX" Plugin:
- Go to Plugins > Plugins Admin.
- Find TextFX in the list, check it, and click Install.
-
Using TextFX to Remove Duplicates:
- Select the text you want to edit.
- Navigate to TextFX > TextFX Tools.
- Choose Sort lines case insensitive (at the top of the menu) and check the box for Remove duplicates. This will keep your empty lines intact.
Method 2: Manual Modification
If you prefer not to install plugins, you can do the following:
- Select All Text: Press
Ctrl + A. - Copy to a New Document: Open a new tab with
Ctrl + N, and paste your text. - Use the Find Feature: Press
Ctrl + Hto open the Find and Replace dialog. - Replace Non-empty Lines: Use the following settings:
- Find what:
^(?!\s*$).*$ - Replace with: (Leave this blank)
- This will match all lines that are not empty, essentially keeping your empty lines.
- Find what:
- Click "Replace All" to remove duplicates while maintaining empty lines.
Practical Example
Suppose you have the following text:
Hello World
Hello
Hello World
Goodbye
Goodbye
When you apply the methods above, you should get the following result:
Hello World
Hello
Goodbye
Why This Matters
Keeping empty lines is crucial for document formatting. It can aid readability and help delineate sections or categories in your text, especially when working with lengthy documents or code.
Additional Tips

Ctrl + Hfor Find and Replace.
