Ultimate Guide to Capitalization Rules

Mastering capitalization is key to professional communication. Here are the modes we offer:

  • Sentence Case: Only the first letter of the first word and proper nouns are capitalized. This is the standard for most English writing, ensuring a natural and readable flow.
  • Title Case: The first letter of every major word is capitalized. Perfect for headlines, book titles, and email subjects to grab attention (e.g., "The Quick Brown Fox").
  • UPPER / lower Case: Converting to all caps is useful for emphasis or acronyms, while lowercase is great for normalizing messy data input.

Naming Conventions for Developers

For programmers, consistent naming is not just a preference; it's a requirement. Our tool instantly translates natural language into code-friendly formats:

camelCase: Standard in JavaScript, Java, and Swift. The first word is lowercase, and each subsequent word starts with a capital letter, with no spaces (e.g., getUserID, calculateTotal).

snake_case: All lowercase letters separated by underscores (e.g., database_connection). This is the go-to format for Python variables and database column names to avoid compatibility issues.

Frequently Asked Questions (FAQ)

What is the difference between Snake Case and Camel Case?

The main difference is the separator. Snake Case uses underscores (user_name) and is common in Python/SQL. Camel Case uses capital letters for separation (userName) and is standard in JavaScript/Java.

Does it support special characters?

Yes, absolutely. Our tool provides full UTF-8 support. It correctly handles accents, emojis, and special characters from any language without corruption.

Is my text private?

Your privacy is our priority. This tool runs 100% Client-Side. Your text is never sent to our servers. All processing happens locally on your device.

Does it verify grammar?

No, this tool specifically handles capitalization changes. It won't correct spelling mistakes or grammar issues, but it will perfectly standardize the letter case.

Are the word/character counts accurate?
