技术架构与执行机制
String Tokenization & Unicode Case Mapping
Case transformation splits input text into word tokens using whitespace and delimiter boundaries. Title Case applies conditional rules to preserve minor stop-words (e.g. "and", "the", "in", "of") unless positioned at the start of a sentence.
Title Case = text.replace(/\w\S*/g, (w, i) => MinorWords.includes(w) && i > 0 ? w.toLowerCase() : Capitalize(w))技术限制与运行约束
- Acronyms (e.g. NASA, FBI) may be converted to standard capitalized words in Title Case mode unless excluded.

常见问题与解答
How do I fix text accidentally typed in CAPS LOCK?
Paste your text and click "Sentence case" or "lowercase". Your text will immediately convert to proper capitalization.

camelCase joins words with capitalized subsequent letters (myVariableName). snake_case separates lowercase words with underscores (my_variable_name).
Does this tool upload my text to a server?
No. All transformations run 100% locally inside your web browser.
