Common Use Cases & Programming Examples

🚀 Programming & Development

Convert variable names, function names, and class names to match coding conventions across different programming languages.

JavaScript/TypeScript: myVariableName (camelCase)

Python/Ruby: my_variable_name (snake_case)

C#/Java Classes: MyClassName (PascalCase)

Constants: MAX_RETRY_COUNT (CONSTANT_CASE)

CSS Classes: button-primary-large (kebab-case)

🔗 URL Optimization & SEO

Create SEO-friendly URLs and slugs using kebab-case format, which is the standard for web addresses. Search engines prefer lowercase letters with hyphens for better readability and indexing.

Example:

❌ www.example.com/Best Products For Home

✅ www.example.com/best-products-for-home

📝 Content Writing & Documentation

Quickly format headings with Title Case, fix incorrectly capitalized text, or standardize naming conventions across documentation.

🗃️ Database & API Design

Standardize column names, table names, and API endpoint conventions. Most databases prefer snake_case, while JSON APIs often use camelCase.

Frequently Asked Questions

What is camelCase and when should I use it?

camelCase is a naming convention where the first word is lowercase and subsequent words start with capital letters, with no spaces or punctuation. Example: myVariableName. Use camelCase for JavaScript, Java, and TypeScript variable and function names. It's the standard convention in most modern programming languages for local variables and methods.

What's the difference between snake_case and kebab-case?

snake_case uses underscores between words (my_variable_name) and is the standard in Python, Ruby, and database column names. kebab-case uses hyphens (my-variable-name) and is preferred for URLs, CSS classes, and HTML attributes because hyphens are URL-safe and more readable in web contexts.

Which case format should I use for programming?

It depends on your language: JavaScript/TypeScript → camelCase for variables, PascalCase for classes; Python/Ruby → snake_case; CSS → kebab-case; Constants → CONSTANT_CASE; React Components → PascalCase. Always follow your team's style guide or the language's official conventions.

Is my data safe when using this tool?

Absolutely! All text conversion happens locally in your browser using client-side JavaScript. Your text never leaves your device, is not sent to any server, and is not stored anywhere. This ensures complete privacy and security for sensitive data.

How do I create SEO-friendly URLs?

Use the kebab-case or slug-case format for SEO-friendly URLs. These formats use lowercase letters with hyphens, making URLs readable by both users and search engines. For example: "how-to-create-seo-friendly-urls" is better than "How_To_Create_SEO_Friendly_URLs".

What is PascalCase used for?

PascalCase (also called UpperCamelCase) capitalizes the first letter of every word with no spaces: MyClassName. It's the standard for class names in Java, C#, JavaScript/TypeScript, and React component names. It helps distinguish classes from regular variables.

Can I convert multiple texts at once?

Currently, the tool processes one text at a time for optimal performance. However, conversion is instant, so you can quickly process multiple texts by pasting each one sequentially. Each conversion takes less than a second.

Does this tool work offline?

Yes! Once the page is loaded, all conversions happen in your browser without requiring an internet connection. You can bookmark this page and use it offline for local text processing.
