Convert Text Case: UPPER, lower, Title, camelCase

This case converter is for tidying text and preparing identifiers. It offers six modes: all upper case, all lower case, first letter of each word capitalised (Title Case), camelCase for JavaScript variables, snake_case for Python and SQL, and kebab-case for file names and CSS classes. The transform applies to Latin letters; non-Latin scripts stay as they are. Nothing is uploaded.

Frequently asked questions

What does Title Case do to non-Latin text?

Nothing, because those scripts have no letter case. The mode is designed for Latin headings.

How does camelCase treat spaces?

It drops spaces and non-alphanumeric characters and capitalises each following part, so “hello world example” becomes helloWorldExample.

What is the difference between snake_case and kebab-case?

Both replace spaces with a separator: snake_case uses an underscore for Python and SQL, kebab-case uses a hyphen for file names and CSS classes.
