About camelCase Converter
camelCase starts lowercase and capitalizes each subsequent word: `userAccountId`. It is the standard identifier style in JavaScript, Java, C# methods and Swift, and it is what JSON APIs built by those ecosystems tend to emit. The conversion splits on spaces, hyphens, underscores and existing case boundaries, so it handles input already in another convention.
How to use it
- Paste the text you want to run through camelcase converter.
- There is nothing to configure — the result updates as you type.

Questions
What is the difference from PascalCase?
Only the first letter. camelCase starts lowercase (`userName`), PascalCase starts uppercase (`UserName`). By convention camelCase names variables and methods; PascalCase names classes and types.
How are acronyms handled?
They are normalized — "parse HTML file" becomes `parseHtmlFile`, not `parseHTMLFile`. Most style guides prefer this, because `parseHTMLFile` makes the word boundary after the acronym ambiguous.
