Case Changer – Change Text Case Online
Paste text once and convert it to uppercase, lowercase, sentence case, title case, camelCase, PascalCase, snake_case or kebab-case. The converter runs in your browser, so your text is not uploaded to FixCaseNow.
How to change text case
Use the main converter when a document, heading, list or code identifier has the wrong capitalisation.
- Paste or type the text you want to fix.
- Choose the output style, such as UPPERCASE, lowercase, Title Case, camelCase or snake_case.
- Check the converted result, then copy it to your document, website or code editor.
Text case examples
The words stay the same while their capitalisation and separators change.
| Use | Input | Result |
|---|---|---|
| UPPERCASE | project launch notes | PROJECT LAUNCH NOTES |
| lowercase | PROJECT LAUNCH NOTES | project launch notes |
| Sentence case | PROJECT LAUNCH NOTES | Project launch notes |
| Title Case | project launch notes | Project Launch Notes |
| camelCase | project launch notes | projectLaunchNotes |
| snake_case | project launch notes | project_launch_notes |
| kebab-case | project launch notes | project-launch-notes |
Which case should you use?
Sentence case is usually the clearest choice for normal prose. Title Case is useful for headings when your style guide requires it. Developers commonly use camelCase for JavaScript variables, snake_case for Python identifiers and kebab-case for URLs. UPPERCASE is best reserved for short labels, constants or deliberate emphasis.
