Frequently Asked Questions

What is camelCase?
camelCase starts with a lowercase letter and capitalizes the first letter of each subsequent word. Example: getUserProfile.
What's the difference between camelCase and PascalCase?
PascalCase (also called UpperCamelCase) capitalizes the first letter too. Example: GetUserProfile.
Does this work with multi-line text?
Yes. Each line is converted independently, preserving the structure of your text.
How does it handle abbreviations like 'HTML' or 'API'?
Abbreviations are intelligently lowercased in snake_case (html_parser) and kept uppercase in CONSTANT_CASE (HTML_PARSER).
