How to convert case
- Paste your text into the box.
- Click the case style you want.

- Repeat with a different style if you need to compare.

Frequently asked questions
What is the difference between Title and Sentence case?
Title Case capitalizes the major words (great for headings); Sentence case capitalizes only the first word, like normal prose.
When would I use camelCase or snake_case?
These are programming conventions for naming variables and functions. camelCase is common in JavaScript; snake_case in Python and databases.
Does it handle accented letters?
Yes, accented characters are uppercased and lowercased correctly.
