What case formats are supported?

We support lowercase, UPPERCASE, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, dot.case, path/case, and Header-Case.

How does camelCase conversion work?

The tool splits your text into individual words, lowercases the first word, capitalizes the first letter of each subsequent word, and joins them without spaces.

Can I convert programming variable names?

Yes. Paste a variable name in any format (e.g. myVariableName) and convert it to snake_case, kebab-case, CONSTANT_CASE, or any other format instantly.

What is the difference between camelCase, snake_case, and kebab-case?

camelCase joins words with no separator and capitalizes each word after the first (e.g. myVariable). snake_case uses underscores (my_variable). kebab-case uses hyphens (my-variable). Each is common in different languages and contexts.

How do I fix text typed with Caps Lock on?

Paste your accidentally capitalized text and select 'lowercase' or 'Sentence case' to fix it instantly. No need to retype — the tool preserves your original words while correcting the case.

Which naming convention should I use for code?

It depends on your language: JavaScript/TypeScript uses camelCase for variables and PascalCase for classes. Python uses snake_case. CSS classes use kebab-case. Constants typically use CONSTANT_CASE across most languages.

How to Use the Case Converter

Paste or type your text in the input area, then click any of the 12 case format buttons to convert instantly. The output updates in real time and can be copied with one click. The tool intelligently splits words by detecting camelCase boundaries, underscores, hyphens, dots, and spaces so it works with both natural language and programming identifiers. Use our word counter to check your text length before converting.

What Are Naming Conventions?

Programming languages and style guides use specific case conventions for variable and function names. JavaScript typically uses camelCase for variables and PascalCase for classes. Python prefers snake_case. CSS custom properties use kebab-case. Environment variables and constants use CONSTANT_CASE. URL slugs use lowercase with hyphens. Converting between these naming conventionsmanually is tedious and error-prone, especially with multi-word identifiers.

Common Use Cases

Convert API response field names from snake_case to camelCase for JavaScript consumption. Transform class names to kebab-case for CSS selectors. Generate CONSTANT_CASE names for configuration keys. Convert Title Case headings to URL-friendly slugs. Remove duplicate lines from your converted output with the Text Repeater & Manipulator. Batch convert a list of variable names when migrating code between languages or style guides. If your identifiers contain special characters, try the string encoder/decoder first. The tool also handles Sentence case for natural language and Header-Case for HTTP headers.
