Frequently Asked Questions
What case styles does this tool support?
It converts to UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, and aLtErNaTiNg CaSe — all generated at once from a single input.
Does it work with camelCase or snake_case input?
Yes. The converter recognizes word boundaries in camelCase, PascalCase, snake_case, kebab-case, and space-separated text, then re-splits and rebuilds each case style correctly.
Is there a character limit?
The input box accepts up to 500,000 characters, which comfortably covers variable names, headlines, and full paragraphs.
How does Title Case decide which words stay lowercase?
Title Case capitalizes every word except a fixed list of minor words — articles, coordinating conjunctions, and short prepositions such as "a," "the," "and," and "of" — and it always capitalizes the first and last word of the text regardless of that list.
Does this tool store or upload my text?
No. Every conversion runs locally in your browser using JavaScript — nothing is uploaded or saved anywhere.
How does the converter split camelCase or snake_case words?
It inserts breaks before uppercase letters that follow a lowercase letter or digit, and before underscores, hyphens, and spaces, so "helloWorldExample" or "hello_world_example" both split cleanly into "hello," "world," "example."
