- Choose the case format that matches your destination.
- Check the result and use Copy to place it on your clipboard.
Common uses
- Standardize inconsistent headings or spreadsheet labels.
- Turn a phrase into a camelCase or snake_case identifier.
- Fix text accidentally typed with Caps Lock enabled.
Good to know
Automated title case cannot infer every editorial style rule for short words, names, or acronyms. Review important headings before publishing. Conversion happens in your browser.
Frequently asked questions
What is the difference between camelCase and snake_case?
camelCase joins words and capitalizes each word after the first; snake_case joins lowercase words with underscores.
Will formatting such as bold text be preserved?
No. The converter works with plain text, so rich-text formatting is not retained.
