Frequently Asked Questions

Title Case capitalizes the first letter of every word. This tool capitalizes all words for simplicity. In strict editorial style (AP, Chicago), short prepositions and articles like the, a, of, in are not capitalized unless they're the first or last word.

camelCase starts with a lowercase letter: myVariableName. It's used in JavaScript, Java, and Swift for variable and function names. PascalCase (also called UpperCamelCase) starts with an uppercase letter: MyClassName. It's used in C#, PHP, and most languages for class names.

snake_case (underscores) is used in Python for variables and function names, database column names, and file names in Linux. kebab-case (hyphens) is used in HTML/CSS class names, URL slugs, and CLI flag names because hyphens are URL-safe and more readable in hyperlinks.

Common Use Cases

Variable Names in Code

Convert a human-readable label to camelCase (JavaScript) or snake_case (Python, PHP) for use as variable or function names instantly.

URL Slug Preparation

Convert page titles to lowercase before pasting into a URL slug field, or use kebab-case output directly as a clean SEO-friendly URL path.

Database Columns

Transform snake_case database column names into Title Case for display in reports and dashboards without touching the schema.

Headline Formatting

Apply consistent Title Case to article headings and subheadings across a CMS. Fix all-lowercase or ALL-CAPS titles pasted from a document in seconds.

Data Normalization

Lowercase inconsistent form submissions before storing to a database to avoid duplicates like "London", "LONDON", and "london" being treated as different values.
