Frequently Asked Questions

What programming languages use camelCase?

Python, Ruby, and Rust commonly use camelCase for variable and function names. It's also the standard for SQL database column names and table names.

Is camelCase better than camelCase?

Neither is inherently better—it depends on context. Use camelCase for Python/Ruby code and databases. Use camelCase for JavaScript and Java. Consistency within your project matters most.

Can I convert multiple lines at once?

Yes! Paste multiple lines of text and the converter will process each line independently, preserving the line structure.
