Questions
How does it split words for camelCase and snake_case?
It breaks on spaces, punctuation, hyphens and underscores, and between a lowercase letter and a capital. Runs of capitals are kept together, so XMLHttpRequest becomes xml_http_request. Apostrophes are dropped, so don't becomes dont.
Are lines converted separately?
For camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE, yes: each line becomes its own identifier, so you can convert a list in one go. The other cases keep your line breaks as they are.
Does Title Case follow a style guide?
No. It capitalises the first letter of every word and lowercases the rest, including short words like "of" and "the". Acronyms such as NASA become Nasa, so check names before you use the result.
What happens to Hindi and other scripts without capitals?
Their letters stay as they are. Spaces and punctuation are still turned into _ or - for the programming cases.
Is my text uploaded?
No. Everything runs in your browser.
