About this Case Converter

Formatting text to the right case can be tedious to do by hand — especially for long paragraphs, code variables, or headings. This tool converts any text into 7 different formats with a single click.

All 7 formats explained

  • UPPER CASE — Every letter becomes uppercase. Use for headings, acronyms, or emphasis. Example: HELLO WORLD
  • lower case — Every letter becomes lowercase. Useful for normalising text or code values. Example: hello world
  • Title Case — First letter of every word is capitalised. Standard for article titles, book names, and headings. Example: Hello World
  • Sentence case — Only the first letter of the first word is capitalised. Standard for normal sentences and paragraphs. Example: Hello world
  • camelCase — Words joined together, each new word starting with a capital letter, no spaces. Used in JavaScript and many programming languages for variable names. Example: helloWorld
  • snake_case — Words joined by underscores, all lowercase. Common in Python, databases, and file names. Example: hello_world
  • kebab-case — Words joined by hyphens, all lowercase. Used in URLs, CSS class names, and HTML attributes. Example: hello-world

Who uses this tool

Writers use it to quickly fix accidental caps-lock text. Developers use it to convert variable names between coding conventions. Content creators use it to format article titles and headings consistently. Anyone who copies text from one source and needs it reformatted before using it elsewhere.

Frequently Asked Questions

What are the different text case types? +

Common text case types include: lowercase (all letters small), UPPERCASE (all letters capital), Title Case (First Letter Of Each Word Capitalised), Sentence case (Only the first letter of the sentence is capitalised), camelCase (used in programming, noSpacesBetweenWords), and snake_case (words_separated_by_underscores).

What is camelCase and where is it used? +

camelCase writes multiple words together with no spaces, capitalising the first letter of each word except the first (e.g. 'myVariableName'). It is widely used in JavaScript, Java, and many other programming languages for variable and function names.

What is the difference between Title Case and Sentence Case? +

In Title Case, the first letter of every major word is capitalised (prepositions and articles are usually lowercase). In Sentence case, only the first word of the sentence and proper nouns are capitalised. Title Case is used for headings; Sentence case is standard for regular text.

How do I convert text to snake_case or kebab-case for programming? +

This case converter focuses on common text cases. For programming-specific formats like snake_case (word_one_word_two) or kebab-case (word-one-word-two), you may need to additionally replace spaces with underscores or hyphens. Many code editors have built-in shortcuts for these transformations.

Why is consistent text casing important for SEO and headings? +

Consistent use of Title Case for H1 headings and product names helps with brand recognition and readability. Google does not penalise for case choice in headings, but consistency signals a professional, well-maintained site. Most style guides recommend Sentence case for body text and Title Case for headlines.
