关于 列表对比
查找交集和两侧独有项目
Comparisons are only meaningful when the normalization rules match the question. Decide whether case, whitespace, empty lines, order, and duplicate entries carry meaning before interpreting the result.
如何使用这个开发者工具
- Paste the left and right lists into their respective inputs.
- Choose whether to ignore case, trim whitespace, remove empty lines, or treat duplicates specially.
- Review the intersection and one-sided results, then copy the list that matches the next workflow.
隐私与数据处理
List comparison runs locally and does not require a server request. Use representative identifiers rather than pasting an unrestricted export that contains personal or confidential values.

常见问题
Why do visually identical items appear different?
They may differ by spaces, tabs, line endings, case, Unicode normalization, or an invisible character. Apply only the normalization that matches your data contract.
Does order affect the comparison?
The set-style result focuses on membership. If order matters, inspect the original lists or use a sequence-aware diff as a second step.
Are duplicate lines preserved?
That depends on the selected comparison behavior. Check the result labels and use the duplicate-aware option when counts matter.
