Case Converter
Convert text between common case styles. Choose a mode or convert all at once.
How it works
- snake_case and kebab-case split on spaces and punctuation, then join with _ or -
- Title Case capitalizes each whitespace-separated word
- Sentence case lowercases the text, then capitalizes after . ! ?
Examples
- “Hello World Example Text” → Title Case stays similar; snake_case → hello_world_example_text
- UPPER → HELLO WORLD EXAMPLE TEXT
- kebab-case → hello-world-example-text
- Sentence case → “Hello world example text.” (first letter + after .!?)

FAQ
What is Title Case?
Each word starts with a capital letter and the rest is lowercase — useful for headlines and names.
When should I use snake_case or kebab-case?
snake_case is common in code identifiers; kebab-case is common in URLs and CSS class names.
Does conversion change my original text permanently?
No. The input box stays editable; output is a separate field you can copy.
What is sentence case?
Sentence case lowercases the text, then capitalizes the first letter and letters after . ! ? — common for body copy and many modern UI labels.
