Compare two text files in Notepad++


Notepad++ is the most popular Text Editor for the Windows operating system, one of its widely used features of it is text compare. You can compare two text files (be it XML, JSON, CSV, Java, Python, HTML, JavaScript, CSS code, any text file) to know if they are identical, do they have something missing, what is the difference between the two files.

If you do not see the Compare tool under the Plugins menu, then you would need to install it using the Plugin Admin (Manager) - follow this tutorial to install it - https://code2care.org/q/notepad-plus-plus-compare-option-unavailable
