What the Case Converter does
The case converter reformats any text into the capitalisation style you need, from headline Title Case to developer-friendly camelCase and snake_case.
How it works
The tool applies a set of text transformations to your input. Title Case capitalises the first letter of each significant word, Sentence case capitalises only the first letter of each sentence, and the programming cases join words with the separators developers expect.
It handles the edge cases that trip up manual editing, such as small words in titles and punctuation between sentences, so the output is consistent every time.
