Questions and answers

What case formats are supported?
13 formats: camelCase, PascalCase, snake_case, SCREAMING_SNAKE_CASE, kebab-case, Train-Case, dot.case, path/case, Title Case, Sentence case, UPPERCASE, lowercase, and space-separated words.
Does it auto-detect the input format?
Yes, the tool analyzes your input to detect whether it's camelCase, snake_case, kebab-case, etc. and highlights the detected format in the output grid.
Can I convert multiple words at once?
Yes, paste multiple identifiers (one per line) for bulk conversion. Each line is converted independently across all 13 output formats.
How does it handle acronyms like 'XML' or 'API'?
The tokenizer detects case transitions to split words. 'XMLParser' becomes 'xml-parser' in kebab-case and 'xml_parser' in snake_case, treating runs of capitals as separate words.
Is it free?
Yes, Free to use and privacy-first by design. All conversion happens in your browser with no data collection or server communication.
