文本清理工具

移除多余的空白字符、规范化换行符、修正花引号，并清理粘贴而来的文本。

如何使用本工具

1
Paste your messy text into the input box.
2
Toggle the options you want: trim lines, collapse spaces, remove line breaks, replace tabs, and fix smart quotes.
3
Read the cleaned result in the lower box, which updates live as you type or change options.
4
Click 'Copy clean text' to copy the result to your clipboard.

从PDF、网站或Microsoft Word中粘贴的文本，通常会带有隐藏的杂质：花引号（弯引号）、长破折号、软连字符、双空格、行尾空格，以及制表符与空格的混用。本工具会将这一切规范化为干净的纯文本，可直接粘贴到代码编辑器、CMS表单或其他要求严格的环境中。

Cleaning a quote pasted from a Word document before dropping it into source code, where curly apostrophes would cause syntax errors.
Flattening multi-line text copied from a PDF into a single line for a spreadsheet cell or search field using the remove-line-breaks toggle.
Removing the trailing spaces and tab-indented lines that sneak in when copying from a chat app or rendered web page.
Normalizing en-dashes and em-dashes to plain hyphens so a CSV or plain-text export stays ASCII-safe.
Tidying marketing copy pasted into a CMS field so double spaces after sentences collapse to single spaces.
Preparing a code comment or commit message by stripping the smart quotes and ellipses an editor auto-inserted.

为什么花引号是不好的？▼

它们会破坏代码语法、损坏CSV导出，并且在某些环境中无法正确显示。用于文档没有问题；但用于技术内容时，请将其替换掉。
