How to Use the Text Case Converter

Common Mistakes to Avoid

Pasting text that already contains inconsistent spacing—clean extra spaces before converting to prevent doubled gaps.

Expecting brand names or acronyms to stay capitalized in sentence case. Double-check proper nouns after conversion.

Copying formatted text straight from a CMS. Use plain text input to avoid hidden HTML entities sneaking into the output.
