- Enter the modified text on the right.
- Click 'Compare'.
- View added lines (green), removed lines (red), and unchanged lines with color coding.
Key Features
- Line-by-line difference comparison

Frequently Asked Questions
文本差异算法如何工作？▼
工具使用逐行差异算法（类似Unix diff）比较原始和修改文本的每一行。识别三种变更类型：添加行、删除行和未更改行。这与Git显示代码更改的方法相同。
可以比较格式化的JSON或代码文件吗？▼
可以。直接粘贴代码或JSON。工具逐行比较，一致的格式能产生更清晰的差异。JSON建议先美化两个版本以便更容易发现结构变化。压缩的代码会显示为一个大的变更。
工具能检测移动或重新排序的行吗？▼
基本差异算法将移动的行视为旧位置的删除和新位置的添加。不会显示'行从X移动到Y'。要检测重排，查找内容相同的绿色（添加）和红色（删除）匹配行。
