It looks for lowercase-to-uppercase transitions (helloWorld → hello World) and runs of capitals followed by a lowercase letter (XMLParser → XML Parser), plus standard delimiters like spaces, hyphens, and underscores.

Every Case Style, One Conversion
Different contexts demand different case conventions — CSS classes use kebab-case, JavaScript variables use camelCase, Python constants use CONSTANT_CASE, database columns often use snake_case, and URLs need clean slugs. Manually retyping the same phrase in five different styles is tedious and error-prone.
This tool detects word boundaries intelligently — whether your input is already camelCase, space-separated, or a mix of punctuation and casing — and converts it to every common style simultaneously.
How It Works
1. Paste Your Text
Any format works — spaces, camelCase, hyphens, or mixed.
2. See Every Style
All 10 case conversions update instantly as you type.
3. Copy What You Need
Copy any individual result with one click.
4. Generate a Slug
Switch tabs for full control over URL slug formatting.
Generates a clean, URL-safe slug — strips accents/diacritics, removes special
characters, and normalizes to lowercase with your chosen separator.

How does this detect word boundaries in camelCase input?
What makes a good URL slug?
Lowercase, hyphen-separated (not underscores — search engines treat hyphens as word breaks but not underscores), essential keywords only, and under about 60 characters.
