About Text Case Conversion
Text case conversion is essential for programmers and writers who need to switch between naming conventions. Different contexts require different formats: camelCase in JavaScript, snake_case in Python, kebab-case in CSS, PascalCase for class names, and CONSTANT_CASE for environment variables.
Paste or type your text, select the desired case format from the dropdown, and the converted output appears instantly. The tool intelligently splits words from any input format — it recognizes camelCase boundaries, underscores, hyphens, and spaces before applying the new case convention.
Case conversion is used daily for converting variable names between programming languages, formatting headings and titles in content writing, preparing database column names or API field names, converting between CSS class naming conventions, and standardizing text formatting across documents.
The tool supports nine formats: UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, and CONSTANT_CASE. Title Case capitalizes the first letter of each word, while Sentence case capitalizes only the first word. Programming formats join words without spaces using their respective separator conventions.
