Frequently asked questions

Does camelCase and snake_case work on multi-word input?

Yes. The converter splits your text into words (handling spaces, hyphens, and existing camelCase), then rebuilds in the target format.

Does it work on multiple lines?

Yes. Each line is converted independently, preserving your paragraph structure.

What is the difference between Title Case and Sentence case?

Title Case capitalises every word. Sentence case capitalises only the first word of each line, like a normal sentence.

Can I convert code variable names?

Yes. The converter handles camelCase, PascalCase, snake_case, and kebab-case in both input and output, making it useful for renaming variables across naming conventions.
