About This Calculator

It is useful both for polishing written content (title case for headings, sentence case for paragraphs) and for developers normalizing identifiers, filenames, and variable names to a team convention.
Conversion runs entirely in your browser.

Frequently Asked Questions
What is the difference between camelCase and PascalCase?
camelCase starts with a lowercase letter (myVariable); PascalCase starts each word with an uppercase letter (MyVariable). Both remove spaces.
Does title case handle small words like "and" correctly?
The basic title-case output capitalizes every word. For refined rules (not capitalizing articles/prepositions), check the refined title-case tool.
