FAQ
Does it work with Chinese text?
Chinese characters have no upper or lower case, so the tool targets the Latin alphabet. Any Chinese content passes through unchanged.
What is the difference between camelCase and PascalCase?
camelCase leaves the first word lowercase, as in myVariable. PascalCase capitalizes the first letter of every word, as in MyVariable.
Can I convert several lines at once?
Yes. Paste multi-line text and each line is converted separately.
How does snake_case work?
Choose the snake_case mode and spaces and special characters between words become underscores while every letter is lowercased.
