About the Text Case Converter
The Text Case Converter changes the capitalization of any text in one click. It supports UPPERCASE, lowercase, Title Case, Sentence case, camelCase and snake_case, which covers both writing and programming needs.
It changes letter case only: punctuation and line breaks are kept, while rich formatting such as bold or links is not preserved. Everything runs in your browser with JavaScript. Nothing you type is uploaded to our server, so it is safe to use with private data.
How to use it
- Paste your text into the input area.
- Pick the case you need.
- Copy the converted text from the output area.
Common uses
- Fixing text that was typed with Caps Lock on.
- Formatting headings and titles consistently.
- Turning a phrase into a variable name (camelCase) or a database column name (snake_case).
- Creating clean labels and filenames.
Tips
- Title Case capitalizes every word; check small words like "and" or "of" if your style guide keeps them lowercase.
- Sentence case lowercases proper nouns too, so recheck names afterwards.
