Common use cases

  • Fixing a headline that was typed with caps lock on.
  • Converting a column of labels into camelCase or snake_case identifiers for code.
  • Producing CONSTANT_CASE names for environment variables.
  • Turning a product name into kebab-case for a CSS class or file name.

Limitations and things to watch for

  • Title Case uses an editorial word list for short words (a, an, and, as, at, but, by, for, in, nor, of, on, or, the, to, up, via). Style guides disagree on these, so review the output for published headlines.
  • Sentence case capitalises the first letter of each sentence and lowercases the rest; it cannot know that a word is a proper noun, so names need a manual pass.
  • Code cases (camel, Pascal, snake, kebab, constant) strip punctuation and treat it as a word boundary, which is what identifiers require.

Frequently asked questions

What is the difference between Title Case and Sentence case?
Title Case capitalises the first letter of every significant word, as in "The Quick Brown Fox". Sentence case capitalises only the first word of each sentence, as in "The quick brown fox".
Does it handle accented and non-Latin characters?
Yes. Conversion uses Unicode-aware case mapping, so é becomes É, ß is handled correctly and scripts without case, such as Arabic or Chinese, pass through unchanged.
Can it convert a whole list at once?
Yes. Paste as many lines as you like — every line is converted and line breaks are preserved.
Is my text uploaded?
No. Case conversion runs in your browser and nothing is sent to a server.
