文本大小写转换器

1. 输入文本 — 直接输入或粘贴。
2. 查看所有转换 — 实时网格同时显示12种格式。
3. 一键复制 — 点击结果旁的复制图标。

包括UPPERCASE、lowercase、Title Case、camelCase、snake_case、kebab-case等12种格式——全部同时可用。

作家使用Title Case作为标题。开发者在编程语言之间转换变量名。内容创作者使用alternating case制作表情包。此工具即时转换。

Different programming languages prefer different naming conventions: JavaScript uses camelCase, Python prefers snake_case, CSS uses kebab-case, and constants are written in CONSTANT_CASE. This tool lets you switch between all of them without manual editing.

Unlike other converters that show one format at a time, this tool displays all 12 conversions simultaneously in a clean grid. Each result has a dedicated copy button, so you can grab exactly the format you need without extra clicks.
