Text Compare
Compare two texts and find the differences.
Online text comparator: find differences between two versions
Comparing two versions of a text to identify changes is a common task in programming, writing, document editing, and quality control. Our text comparator analyzes both versions line by line and visually highlights the differences: added lines appear in green with the "+" symbol, deleted lines appear in red with the "-" symbol, and unchanged lines are shown without color.
In software development, diffs are fundamental for code reviews, where team members review changes before merging them into the main branch. In publishing, comparing versions allows tracking edits made by different reviewers on a document.
The tool shows a summary with the total number of added, deleted, and equal lines, and immediately tells you if the texts are identical. All comparison runs in your browser without sending data to external servers, making it safe for comparing proprietary code or confidential information.
Frequently asked questions
How does the comparison work?
The tool splits both texts into lines and compares them one by one. When a line from the original text does not match the corresponding line in the modified text, the original is marked as deleted (red) and the new one as added (green). Lines that are exactly the same are shown without highlighting. This method is effective for detecting specific changes in structured texts.
Can I compare source code?
Yes, the comparator works perfectly with source code in any programming language. You can paste JavaScript, Python, HTML, CSS, or any other language snippets. The view uses monospaced font and preserves indentation, making it easy to identify changes in code structure, renamed variables, or modified logic.
Does it detect changes in line order?
Yes, the comparison is sensitive to line order. If you move a block of text from one position to another, the tool will show it as deleted lines in the original position and added lines in the new position. This is useful for detecting code reorganizations, reordered paragraphs, or changes in element sequence in configuration files.
