About this tool
Word boundaries are detected from spaces, hyphens, underscores, and camelCase/PascalCase transitions, so the tool correctly re-splits already-cased input (like converting "helloWorld" to "hello world" or "hello-world") before reassembling it in the target case.
100% client-side — nothing you type is uploaded, logged, or stored.
Frequently asked questions
How does the tool detect word boundaries?
It splits on spaces, hyphens, and underscores, and also detects camelCase/PascalCase boundaries (a lowercase or digit followed by an uppercase letter), so text typed as "helloWorld", "hello-world", or "hello_world" all convert the same way.
What's the difference between camelCase and PascalCase?
camelCase starts with a lowercase letter (helloWorld); PascalCase capitalizes every word including the first (HelloWorld). Both are common in programming — camelCase for variables/functions in many languages, PascalCase for class/type names.
