Diff-Viewer

The Diff Viewer tool helps you compare two text files and identify differences line by line. It uses the Longest Common Subsequence (LCS) algorithm to accurately detect additions, deletions, and unchanged lines.

Enter your original text in the left panel and modified text in the right panel. Click the Compare button to generate a diff. The results show added lines in green, removed lines in red, and unchanged lines without highlighting.

You can customize the comparison by enabling 'Ignore Whitespace' to treat multiple spaces as single spaces, or 'Ignore Case' to make the comparison case-insensitive. These options help identify substantive changes rather than formatting differences.
