Frequently Asked Questions
Common questions about text comparison
How does text comparison work?
The tool uses a diff algorithm to compare two texts line by line, identifying which lines are the same, which are added, and which are deleted. Similar to the diff function in code version control (like Git).
What is the difference between split view and unified view?
Split view: Left and right columns displayed side by side, left shows original text, right shows modified text, easy for intuitive comparison. Unified view: All differences merged and displayed in one column in order, using +/- prefixes to mark additions and deletions, similar to Git diff output.
Can I compare code?
Of course. This tool is perfect for comparing code changes, using monospace font display, maintaining code indentation. Whether checking code modifications, reviewing commits, or comparing configuration files, it can handle it.
Will large text affect performance?
For general documents and code files (within a few thousand lines), performance is good. For very large files, there may be brief delays. If you encounter performance issues, it is recommended to compare large files in segments.
How to export comparison results?
Click the "Copy Diff" button to copy the unified format diff result (with +/- prefixes), this format is compatible with standard diff output and can be pasted into documents or emails for sharing.
