Frequently Asked Questions
What is the difference between Title Case and Sentence case?
Title Case capitalises the first letter of every word. Sentence case capitalises only the first letter of the first word in each sentence, like a normal paragraph.
Can I convert variable names between camelCase and snake_case?
Yes. Paste your identifier and select the target case style. The tool correctly splits on case boundaries and separators to produce the right output.
Does the tool handle non-English characters?
Yes. The converter uses the browser's built-in Unicode casing rules, so accented characters like é, ü, and ñ are cased correctly.
