Text Case Converter
Every programming language and style guide seems to prefer a different way of writing multi-word identifiers — this converts freely between the common naming conventions, from plain title case to the camelCase and snake_case styles used in code.

How the text case converter works
Text is first split into individual words (breaking on spaces, hyphens and underscores), then reassembled according to the chosen case style's specific capitalisation and separator rules.
Worked example: 'CalculatorHub is fast' converted to each style
- camelCase: calculatorHubIsFast.
- snake_case: calculatorhub_is_fast.
- kebab-case: calculatorhub-is-fast.
- Title Case: Calculatorhub Is Fast.
Common mistakes to avoid
Assuming this tool preserves existing internal capitalisation, like 'CalculatorHub'
Word-splitting here is based on spaces, hyphens and underscores only — a single word like 'CalculatorHub' with no separator isn't split into 'Calculator' and 'Hub', so case-converting it treats the whole thing as one word rather than two.
Using the wrong case convention for a given programming language's typical style
Different languages have different naming conventions by community norm — JavaScript variables are typically camelCase, Python typically snake_case, and CSS classes and URL slugs typically kebab-case. Using the 'wrong' one won't break anything technically, but goes against common convention.
Frequently asked questions
Why do different programming languages prefer different naming cases?
It's largely historical convention within each language's community rather than a technical requirement — JavaScript and Java favour camelCase, Python and Ruby favour snake_case, and these conventions became self-reinforcing as more code was written in each style within each ecosystem.
What's the difference between camelCase and PascalCase?
camelCase starts with a lowercase letter (calculatorHub); PascalCase (not directly offered here) starts with an uppercase letter (CalculatorHub) — both capitalise subsequent word boundaries the same way.
Why is kebab-case commonly used in URLs specifically?
Hyphens are treated favourably by search engines as word separators (unlike underscores, historically), and kebab-case URLs are considered more readable — this is why the URL Slug Generator produces kebab-case by default.
Does this tool handle numbers within the text correctly?
Numbers are treated as part of whatever word they're attached to and pass through each case conversion largely unchanged, since case conversion rules apply specifically to letters.
