When each case is used
Title Case suits headings and titles. Sentence case matches how normal prose reads. camelCase and snake_case are conventions for naming variables in code — camelCase is common in JavaScript, snake_case in Python and databases.
About the Case Converter
Case Converter changes the capitalisation of text in one click. Choose UPPERCASE, lowercase, Title Case, Sentence case, camelCase or snake_case, and copy the result. Writers use it to fix headings and accidental caps lock, and developers use it to rename variables and keys.
Title Case capitalises the main words in a heading, and the tool keeps short words such as of, and, the in lowercase except at the start. Sentence case capitalises the first letter of each sentence. camelCase joins words and capitalises each after the first, while snake_case uses lowercase with underscores. Proper nouns and acronyms may need manual correction afterwards.
How to use it
- Paste or type your text.
- Click the case style you need.
- Review the result, particularly names and acronyms.
- Copy the output.
Tips and good to know
- Check headings against your style guide, since publishers differ on small words.
- For code, convert one identifier per line.
- Converting to uppercase and back does not restore the original, so keep a copy.
