Frequently asked questions
How does it detect word boundaries in something like 'myVariableName'?
It splits on transitions from lowercase to uppercase letters (as well as spaces, hyphens, and underscores), so camelCase or PascalCase input is correctly broken back into individual words before converting to a new format.
Does it handle numbers in the text?
Numbers are treated as part of the surrounding word and preserved as-is across all formats.
What's the difference between Title Case and Sentence case?
Title Case capitalizes the first letter of every word; Sentence case only capitalizes the first letter of the whole string.
Is my text sent anywhere?
No - conversion happens entirely in your browser.
