A text case converter changes the capitalization and formatting pattern of existing text without requiring you to rewrite it manually. Lamuki's textcase-converter operation supports several common case formats, including UPPERCASE, lowercase, Title Case, Sentence case, camelCase, snake_case, kebab-case, PascalCase, and SCREAMING_SNAKE_CASE. This makes it useful when text needs to follow a particular naming convention, writing style, or formatting pattern.
