Switch between uppercase, lowercase, title, camelCase and more.
在 大写 / 小写 / 标题 / 句首 / 驼峰 / 蛇形 之间转换文本。
A case converter rewrites text between uppercase, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE in one click. It is a small tool that saves real time when renaming variables, cleaning up pasted text or normalising headings. Conversion is instant and entirely local.
大小写转换器一键把文本在大写、小写、词首大写、句首大写、驼峰、帕斯卡、蛇形、短横线和常量式之间互相转换。改变量名、清理粘贴文本、统一标题格式时很省时间。转换即时且完全本地。
It depends on the language convention: camelCase for JavaScript variables, snake_case for Python, kebab-case for URLs and CSS classes, and CONSTANT_CASE for constants.
按语言惯例:JavaScript 变量用驼峰,Python 用蛇形,URL 和 CSS 类用短横线,常量用全大写下划线。
Word boundaries are detected from spaces, hyphens, underscores and existing capitals, so pasted text in almost any format converts correctly.
通过空格、连字符、下划线和已有大写来识别词边界,因此几乎任何格式的粘贴文本都能正确转换。
Case conversion applies to Latin letters. Chinese characters are passed through unchanged, which is the correct behaviour.
大小写只作用于拉丁字母,中文字符原样保留,这是正确行为。
