Case converter

Convert text to UPPER CASE, lower case, Title Case, Sentence case, camelCase and snake_case.

How to use Case converter

Paste your text.
Pick UPPER CASE, lower case, Title Case, Sentence case, camelCase or snake_case.
Copy the converted text.

A good use for this

Fixing text pasted in the wrong case, or reformatting identifiers for code and filenames.

Limits

Conversion is mechanical — Title Case, for example, capitalises words by rule, not by grammar, so proper nouns and small words may need a manual check.
