Technical Architecture & Execution Mechanics

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))

Frequently Asked Questions & Answers

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.

What is the difference between camelCase and snake_case for programmers?

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.

Is there a limit on how much text I can convert?
