Frequently Asked Questions

What text cases are supported? ▾

The tool supports UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE and dot.case conversions.

How does Title Case work? ▾

Title Case capitalises the first letter of every word. Small words like "a", "the" and "of" are kept lowercase unless they appear at the start of the text.

What is the difference between camelCase and PascalCase? ▾

In camelCase the first word is lowercase and subsequent words start with a capital letter (e.g. myVariableName). PascalCase capitalises every word including the first (e.g. MyVariableName).

Can I use this for programming variable names? ▾

Yes. Use camelCase for JavaScript variables, PascalCase for class names, snake_case for Python and Ruby, kebab-case for CSS classes and CONSTANT_CASE for constants.

Does it preserve line breaks? ▾

Yes. Line breaks and paragraph structure are preserved. Only the letter casing changes.

Is there a character limit? ▾

No. You can convert text of any length. All processing happens in your browser with no server calls.
