Frequently Asked Questions (FAQ)
What is a Case Converter, and who is it for?
A Case Converter transforms text into different case formats like uppercase, lowercase, title case, sentence case, camelCase, or snake_case. It’s ideal for writers formatting content, developers naming variables, students preparing documents, and editors ensuring consistent text styles.
What case types are supported?
The tool supports uppercase (ALL CAPS), lowercase (all small), title case (Capitalize Each Word), sentence case (Capitalize first word of each sentence), camelCase (noSpacesWithCaps), and snake_case (underscore_separated_words).
How does each case conversion work?
  • Uppercase: Converts all letters to uppercase (e.g., "hello world" → "HELLO WORLD").
  • Lowercase: Converts all letters to lowercase (e.g., "Hello World" → "hello world").
  • Title Case: Capitalizes the first letter of each word (e.g., "hello world" → "Hello World").
  • Sentence Case: Capitalizes the first letter of each sentence (e.g., "hello. world" → "Hello. World").
  • camelCase: Removes spaces, capitalizes each word except the first (e.g., "hello world" → "helloWorld").
  • snake_case: Replaces spaces with underscores, all lowercase (e.g., "hello world" → "hello_world").
Can I convert large amounts of text?
Yes, the tool handles text of any length, from single words to entire documents. For very large texts, conversion is still instant, but copying may depend on your browser’s clipboard capacity.
Is my text stored or shared?
No, all processing occurs locally in your browser. No data is sent to servers, ensuring privacy for sensitive text like code snippets or personal documents.
How is the history log stored?
The history log is saved in your browser’s local storage, persisting across sessions on the same device and browser. Clear your browser data to reset it. Each entry allows copying the converted text.
Does the tool support non-English text?
Yes, it supports Unicode text, including non-English languages like Spanish, French, or Chinese. Case conversions work for any language with standard alphabetic characters, though special characters remain unchanged.
Is the tool accessible?
Yes, it features high-contrast visuals, keyboard navigation (Tab to focus, Enter to convert), and screen-reader-compatible labels. The textarea and buttons are optimized for accessibility. Feedback is welcome to improve usability.
Can I use this for coding?
Absolutely! Developers can use camelCase and snake_case for variable naming in languages like JavaScript, Python, or Java. Copy converted text directly into your code editor for quick integration.
