Everything you need to know about text comparison
The tool compares text line by line or character by character, highlighting added (green), removed (red), and modified (yellow) content. It uses a sophisticated algorithm to find differences.
Line diff compares entire lines, showing which lines are added, removed, or modified. Character diff shows exact character-level changes within modified lines, highlighting specific differences.
Use this when spaces, tabs, and line breaks don't matter for your comparison. It's useful for comparing code where formatting differences are irrelevant.
