About Case Conversion
Case conversion changes how words are capitalised and joined. Programmers use styles like camelCase, snake_case and kebab-case for variable and file names, while writers use Title Case and Sentence case for headings and prose.
Developers rely on case conversion every day: turning labels into camelCase variables, snake_case database columns, kebab-case URLs and CONSTANT_CASE config keys. Writers use it to fix ALL-CAPS paste-ins, build Title Case headlines and clean up inconsistent capitalisation from spreadsheets.
The converter detects word boundaries from spaces, hyphens, underscores and existing camelCase humps, then rejoins the words in the style you pick. It works on full Unicode text, so accented and non-Latin letters are preserved while only the letter casing changes.
