How do I use the Title Case converter?
Simply paste your text into the input field and select the 'Title Case' option. Our tool will automatically capitalize the first letter of every word while making the rest lowercase.
Is sentence case available?
Yes! Our tool features an intelligent 'Sentence Case' mode that capitalizes the first letter of sentences and handles common punctuation appropriately.
Can I use this for programming or coding?
Absolutely. Developers often use this tool to quickly format strings, convert variable naming conventions, or sanitize text data.
