Case converter

We insert spaces at every case boundary first — fooBarBAZ becomes foo Bar BAZ — then split on any non-alphanumeric character. That's why all of these feed into the same word list:

• helloWorld
• hello-world
• HELLO_WORLD
• Hello World
• hello.world

The output you get depends only on the target style you click — not on how the input was written.

• Acronyms in PascalCase are ambiguous: XMLParser vs XmlParser. Microsoft's .NET guidelines pick the second form for ≥3-letter acronyms; Java picks the first. This tool emits the first form because that's what tokenises round-trip-cleanly.
• Locale-sensitive cases (Turkish İ/ı) use the browser's default locale. If you need Turkish lowercase, set the page locale or run the conversion in Node with an explicit locale.
• Existing punctuation in your input is discarded by the tokeniser. Strip emoji, quotes and parentheses before pasting if you need them preserved.

When to reach for it. Use it to switch text between UPPER, lower, Title, camelCase, snake_case and kebab-case for code, slugs and headings.

When something else is better. It applies mechanical rules; it won’t know that “iOS” or “McDonald” should keep their internal capitals.

The pitfall to watch. Title-case rules differ by style guide (which small words stay lowercase), so blind conversion can over-capitalise.

Everything runs on your device. The values you enter are processed locally in this browser tab — EpitomeTool does not send your input to a server, store it, or log it. That means you can use the tool offline once the page has loaded, and refreshing the tab wipes the slate.
