Case Converter
Switch text or identifiers between common casing and naming conventions.
What this tool does
Case Converter tokenises spaces, hyphens, underscores and mixed identifiers, then rebuilds the words in your chosen style. It supports eleven modes, but mechanical Title Case and Sentence case do not replace editorial review for names, acronyms or style-guide rules. Title Case is not aware of every editorial style guide.
Paste text, choose a case style and copy the converted result.

Troubleshooting
The page becomes slow with a large input or repeat count.
Reduce the input, split the operation into smaller batches and close other memory-heavy tabs. Keep an original copy before retrying.
The result changes after I paste it elsewhere.
Test the destination app, font and character encoding. Some apps normalize whitespace or render Unicode differently.
