FAQ
- Will Chinese text be changed?
- No. The tool only converts ASCII English letters. CJK characters pass through unchanged.
- How does camelCase handle spaces?
- The tool splits English and number words, lowercases the first word, and capitalizes later words.
- Can the result overwrite the input?
- Input and output are separate so the original text is not accidentally lost. Copy the output when ready.
- Is my text uploaded?
- No. Conversion runs locally in your browser and the text is not sent to a server.
