列表添加包围字符
逐项添加左右字面量包围文本；支持1–100层、仅左／仅右、字面量输入／输出分隔符、修剪、空项控制、复制与TXT下载。
使用步骤
如何使用
- Paste a list up to 100,000 characters and choose its literal input separator.
- Enter the left and right text, choose one to 100 wrapping layers, and set cleanup rules.
- Wrap the items, review the result, then copy it or download a text file.
Independent prefixes and suffixes
Left text is prepended and right text is appended to every retained item. Either side may be blank, so the tool can add only a prefix or only a suffix; at least one side must contain one to 20 literal characters. Regular expressions are never executed.
Repeat complete wrapper layers
Choose one to 100 layers. Each layer repeats the complete left text before the item and the complete right text after it, so two bracket layers produce [[item]]. Optional trimming and empty-item removal happen before wrapping. Input is limited to 50,000 parsed items and the estimated result is rejected before construction when it would exceed 500,000 characters.
常见问题
你可能还想知道
Can I add only a prefix?
Yes. Enter left text and leave right text blank. The reverse works for suffix-only output.
What happens to an empty item?
Remove empty items to discard it, or keep empty items to wrap it as the left text followed directly by the right text.
Does multiple layers change the item text?
No. It repeats only the selected left and right wrapper text. The original retained item stays between them.
