## FAQ

### What text cases can I convert between?

Our tool supports: lowercase (all small letters), UPPERCASE (ALL CAPITAL LETTERS), Title Case (First Letter Of Each Word Capitalized), Sentence case (First letter capitalized), and aLtErNaTiNg CaSe (alternating between lower and upper).

### When should I use Title Case?

Use Title Case for headlines, book titles, article titles, and headings. In Title Case, major words are capitalized while minor words (a, an, the, and, but, or, for, nor) remain lowercase unless they start the title.

### What's the difference between Sentence case and Title Case?

Sentence case capitalizes only the first letter of the sentence and proper nouns, like regular writing. Title Case capitalizes the first letter of most words. 'This is sentence case' vs 'This Is Title Case'.

### How do I fix accidental caps lock?

If you've typed a whole paragraph with caps lock on, paste it into our tool and click 'lowercase' to convert it all to small letters. Then use 'Sentence case' to properly capitalize the first letter of each sentence.

### Does the converter preserve special characters?

Yes, our converter only changes letter capitalization. Numbers, punctuation, spaces, emojis, and special characters remain unchanged. Only alphabetic characters (A-Z, a-z) are affected by the conversion.

### Can I convert text for programming?

While this tool handles basic case conversion, it's primarily designed for natural language. For programming-specific conversions like camelCase to snake_case, you may need specialized developer tools.
