When to Use Each Case Style

  • UPPERCASE — headings, acronyms, emphasis (use sparingly online, it reads as shouting).
  • lowercase — normalizing messy text before re-formatting.
  • Title Case — blog titles, headlines, book and movie names.
  • Sentence case — normal body text; the default for most modern web writing.
  • camelCase — JavaScript/Java variable and function names.
  • snake_case — Python variables, database columns, file names.
  • kebab-case — URLs and CSS class names (search engines prefer hyphens in URLs).
  • aLtErNaTiNg — meme text and playful social posts.

Frequently Asked Questions

What is Title Case?
Title Case capitalizes the first letter of every major word. This tool uses the simple style that capitalizes every word — the most common convention for online headings.
What is the difference between camelCase and snake_case?
camelCase joins words with each new word capitalized (myVariableName) and is standard in JavaScript. snake_case joins words with underscores (my_variable_name) and is standard in Python.
