FAQ
Is the text uploaded?
No. The conversion happens locally in your browser, with no server request at all; reloading clears it.
Can camelCase, snake_case and kebab-case convert into each other?
Yes - just pick the target style. The split points are spaces, hyphens, underscores and case boundaries (camelCase becomes camel Case), and a run of capitals read as one abbreviation is kept whole (HTTPResponse becomes HTTP Response).
How are digits handled?
Digits follow the word in front of them (v2 becomes v2 / V2 / v2Beta and so on); they are never split off on their own.
Does it support multi-line text?
Yes, it converts line by line; Sentence case and Title Case work on the start of each line.
