FAQ

Is this case formatter client-side?

Yes. Formatting runs in your browser; no network requests are made by the tool.

What casing styles are supported?

Upper, lower, title, sentence, camelCase, PascalCase, snake_case, SCREAMING_SNAKE_CASE, kebab-case, and dot.case.

Can it format a list line by line?

Yes—enable “Preserve line breaks” to apply the selected case to each line and keep blank lines.

How does it handle acronyms like JSON or API?

Enable “Keep ALLCAPS acronyms” to preserve tokens like JSON/API in Title/Camel/Pascal outputs.

Will punctuation be preserved?

For UPPER/lower/sentence, punctuation stays. For word-join modes (snake/kebab/dot/camel/pascal), most punctuation is treated as a separator.

Why does JSONParser become json_parser in snake_case?

The tool splits common acronym boundaries (JSONParser → JSON + Parser) before joining with underscores.

How is this different from the Online Case Generator?

This tool focuses on fast formatting with line-by-line options and acronym handling; the case generator may offer additional generation-style presets.
