Notepad++ is a popular text editor that has been widely used by programmers and data analysts. It offers many built-in features that make comparing data in Notepad++ a relatively simple task. In this step-by-step guide, we will explore the most efficient ways to compare data in Notepad++.

Step 1: Open two files in Notepad++

The first step in comparing data in Notepad++ is to open the two files you want to compare. To do this, go to File > Open and select the first file you want to compare. Then, repeat the process for the second file you wish to compare. Once both files are open, they should appear as separate tabs in the Notepad++ interface.

Step 2: Enable Compare plugin

Notepad++ comes with a built-in Compare plugin that makes it easy to compare two files. However, this plugin may need to be enabled before use. To enable the Compare plugin, go to Plugins > Plugin Manager > Show Plugin Manager. Then, find the Compare plugin and make sure it is checked. Finally, click on Install to enable the plugin.

Step 3: Compare the files

With the Compare plugin installed and enabled, it is time to compare the two files. To do this, simply go to Plugins > Compare > Compare. This will open a new window that shows the differences between the two files. The Compare plugin highlights the changes in color, making it easy to see where the differences are.

Step 4: Customize the comparison settings

Notepad++ offers several customization options for the Compare plugin. These options allow you to customize the way the plugin compares the files. To access the customization options, go to Plugins > Compare > Set Compare Options. Here, you can choose to ignore case, white spaces, or line endings when comparing the files.

Step 5: Save the compared results

Once you have compared the files and made any necessary adjustments, you may want to save the compared results. To do this, go to Plugins > Compare > Export to… This will allow you to save the compared results in various formats, including HTML, XML, and CSV.


Comparing data in Notepad++ is a straightforward task thanks to its built-in Compare plugin. By following the above steps, you can efficiently compare two files and easily identify the differences between them. Notepad++ is a powerful tool that can save you a lot of time when working with large amounts of data. So, try out these steps and discover how much easier comparing data in Notepad++ can be!
